I'm trying to create a WiFi Log Scanner. Currently we go through logs manually using CTRL+F and our keywords. I just want to automate that process. i.e. bang in a .txt file and receive an output.
I've got the bones of the code, can work on making it pretty later, but I'm running into a small issue. I want the scanner to search the file (done), count instances of that string (done) and output the number of occurrences (done) followed by the full line where that string occurred last, including line number (line number is not essential, just makes things easier to do a gestimate of which is the more recent issue if there are multiple).
Currently I'm getting an output of every line with the string in it. I know why this is happening, I just can't think of a way to specify just output the last line.
Here is my code:
import os
from Tkinter import Tk
from tkFileDialog import askopenfilename
def file_len(filename):
#Count Number of Lines in File and Output Result
with open(filename) as f:
for i, l in enumerate(f):
pass
print('There are ' + str(i+1) + ' lines in ' + os.path.basename(filename))
def file_scan(filename):
#All Issues to Scan will go here
print ("DHCP was found " + str(filename.count('No lease, failing')) + " time(s).")
for line in filename:
if 'No lease, failing' in line:
print line.strip()
DNS= (filename.count('Host name lookup failure:res_nquery failed') + filename.count('HTTP query failed'))/2
print ("DNS Failure was found " + str(DNS) + " time(s).")
for line in filename:
if 'Host name lookup failure:res_nquery failed' or 'HTTP query failed' in line:
print line.strip()
print ("PSK= was found " + str(testr.count('psk=')) + " time(s).")
for line in ln:
if 'psk=' in line:
print 'The length(s) of the PSK used is ' + str(line.count('*'))
Tk().withdraw()
filename=askopenfilename()
abspath = os.path.abspath(filename) #So that doesn't matter if File in Python Dir
dname = os.path.dirname(abspath) #So that doesn't matter if File in Python Dir
os.chdir(dname) #So that doesn't matter if File in Python Dir
print ('Report for ' + os.path.basename(filename))
file_len(filename)
file_scan(filename)
That's, pretty much, going to be my working code (just have to add a few more issue searches), I have a version that searches a string instead of a text file here. This outputs the following:
Total Number of Lines: 38
DHCP was found 2 time(s).
dhcp
dhcp
PSK= was found 2 time(s).
The length(s) of the PSK used is 14
The length(s) of the PSK used is 8
I only have general stuff there, modified for it being a string rather than txt file, but the string I'm scanning from will be what's in the txt files.
Don't worry too much about PSK, I want all examples of that listed, I'll see If I can tidy them up into one line at a later stage.
As a side note, a lot of this is jumbled together from doing previous searches, so I have a good idea that there are probably neater ways of doing this. This is not my current concern, but if you do have a suggestion on this side of things, please provide an explanation/link to explanation as to why your way is better. I'm fairly new to python, so I'm mainly dealing with stuff I currently understand. :)
Thanks in advance for any help, if you need any further info, please let me know.

To search and count the string occurrence I solved in following way
'''---------------------Function--------------------'''
#Counting the "string" occurrence in a file
def count_string_occurrence():
string = "test"
f = open("result_file.txt")
contents = f.read()
f.close()
print "Number of '" + string + "' in file", contents.count("foo")
#we are searching "foo" string in file "result_file.txt"
I can't comment yet on questions, but I think I can answer more specifically with some more information What line do you want only one of?
For example, you can do something like:
search_str = 'find me'
count = 0
for line in file:
if search_str in line:
last_line = line
count += 1
print '{0} occurrences of this line:\n{1}'.format(count, last_line)
I notice that in file_scan you are iterating twice through file. You can surely condense it into one iteration :).

I am reading a text file in python(500 rows) and it seems like:
File Input:
0082335401
0094446049
01008544409
01037792084
01040763890
I wanted to ask that is it possible to insert one space after 5th Character in each line:
Desired Output:
00823 35401
00944 46049
01008 544409
01037 792084
01040 763890
I have tried below code
st = " ".join(st[i:i + 5] for i in range(0, len(st), 5))
but the below output was returned on executing it:
00823 35401
0094 44604 9
010 08544 409
0 10377 92084
0104 07638 90
I am a novice in Python. Any help would make a difference.
There seems to be two issues here - By running your provided code, you seem to be reading the file into one single string. It would be much preferable (in your case) to read the file in as a list of strings, like the following (assuming your input file is input_data.txt):
# Initialize a list for the data to be stored
data = []
# Iterate through your file to read the data
with open("input_data.txt") as f:
for line in f.readlines():
# Use .rstrip() to get rid of the newline character at the end
data.append(line.rstrip("\r\n"))
Then, to operate on the data you obtained in a list, you could use a list comprehension similar to the one you have tried to use.
# Assumes that data is the result from the above code
data = [i[:5] + " " + i[5:] if len(i) > 5 else i for i in data]
Hope this helped!
If your only requirement is to insert a space after the fifth character than you could use the following simple version:
#!/usr/bin/env python
with open("input_data") as data:
for line in data.readlines():
line = line.rstrip()
if len(line) > 5:
print(line[0:5]+" "+line[5:])
else:
print(line)
If you don't mind if lines with less than five characters get a space at the end, you could even omit the if-else-statement and go with the print-function from the if-clause:
#!/usr/bin/env python
with open("input_data") as data:
for line in data.readlines():
line = line.rstrip()
print(line[0:5]+" "+line[5:])
I have been searching for an answer to this, but can not seem to get what I need. I would like a python script that reads my text file and starting from the top working its way through each line of the file and then prints out all the matches in another txt file. Content of the text file is just 4 digit numbers like 1234.
example
1234
3214
4567
8963
1532
1234
...and so on.
I would like the output to be something like:
1234 : matches found = 2
I know that there are matches in the file do to almost 10000 lines. I appreciate any help. If someone could just point me in the right direction here would be great. Thank you.
import re
file = open("filename", 'r')
fileContent=file.read()
pattern="1234"
print len(re.findall(pattern,fileContent))
If I were you I would open the file and use the split method to create a list with all the numbers in and use the Counter method from collections to count how many of each number in the list are dupilcates.
`
from collections import Counter
filepath = 'original_file'
new_filepath = 'new_file'
file = open(filepath,'r')
text = file.read()
file.close()
numbers_list = text.split('\n')
numbers_set = set(numbers_list)
dupes = [[item,':matches found =',str(count)] for item,count in Counter(numbers_list).items() if count > 1]
dupes = [' '.join(i) for i in dupes]
new_file = open(new_filepath,'w')
for i in dupes:
new_file.write(i)
new_file.close()
`
Thanks to everyone who helped me on this. Thank you to #csabinho for the code he provided and to #IanAuld for asking me "Why do you think you need recursion here?" – IanAuld. It got me to thinking that the solution was a simple one. I just wanted to know which 4 digit numbers had duplicates and how many, and also which 4 digit combos were unique. So this is what I came up with and it worked beautifully!
import re
a=999
while a <9999:
a = a+1
file = open("4digits.txt", 'r')
fileContent = file.read()
pattern = str(a)
result = len(re.findall(pattern, fileContent))
if result >= 1:
print(a,"matches",result)
else:
print (a,"This number is unique!")
I am trying to split one file with two articles in it into two separate files with one article in each, for subsequent analysis of the articles. Each article in the initial file has an ID that I want to use to separate the files with, using RE.
Below is the initial input file, with ID number:
166068619 #### "Epilepsy: let's end our ignorance of this neglected condition
Helen Stephens is a young woman with epilepsy [...]."
106899978 #### "Great British Payoff shows that BBC governance is broken
If it was a television series, they'd probably call it [...]."
However, when I run my code, I do get two separate files as an output but they are empty.
This is my code:
def file_split(path_to_file):
"""Function splits bigger file into N smaller ones, based on a certain RE
match, that is used to break the bigger file into smaller ones"""
def pattern_extract(path_to_file):
"""Function identifies the number of RE occurences in a file,
No. can be used in further analysis as range No."""
import re
x = []
with open(path_to_file) as f:
for line in f:
match = re.search(r'^\d+?\t####\t', line)
if match:
a = match.group()
x.append(a)
return len(x)
y = pattern_extract(path_to_file)
m = y + 1
files = [open('filename%i.txt' %i, 'w') for i in range(1,m)]
with open(path_to_file) as f:
for line in f:
match = re.search(r'^\d+?\t####\t', line)
if match:
a = match.group()
#files = [open('filename%i.txt' %i, 'w') for i in range(1, m)]
files[i-1].write(a)
for f in files:
f.close()
return files
Output result is as follows:
file_split(path)
Out[19]:
[<open file 'filename1.txt', mode 'w' at 0x7fe121b130c0>,
<open file 'filename2.txt', mode 'w' at 0x7fe121b131e0>]
I am new to Python and I am not quite sure where the problem lies. I checked some other answers that addressed the multiple file outputs but cannot figure out the solution. Help would be very much appreciated.
There are two problems with your code:
you write only the line matching the ID (actually, just the match itself), not the rest
you are always writing to the last file, as you use i, the loop variable "left over" from the list comprehension
To fix it, you could change the lower portion of your code to this:
y = pattern_extract(path_to_file)
files = [open('filename%i.txt' %i, 'w') for i in range(y)]
n = -1
with open(path_to_file) as f:
for line in f:
if re.search(r'^\d+\s+####\s+', line):
n += 1
files[n].write(line)
But you do not have to read the file two times at all, just to count the matches: Just open another file when the line matches an ID line and directly write to that last file in the list, then close all the files.
open_files = []
with open(path_to_file) as f:
for line in f:
if re.search(r'^\d+\s+####\s+', line):
open_files.append(open('filename%d.txt' % len(open_files), 'w'))
open_files[-1].write(line)
for f in open_files:
f.close()
New user here, and just started Python a few days ago!
My question is:
I need to write a Python stub to print names of image files and whether they are blurry or not. They are considered blurry if the value is > 0.3. There are 5 bits of information in each line, the second bit (index 1) is the number in question. In total there are 1868 lines.
Here is a sample of the data:
['out04-32-44-03.tif,0.295554,536047.6051,5281850.4252,19.8091\n',
'out04-32-44-15.tif,0.337232,536047.2831,5281850.5974,19.8256\n',
'out04-32-44-27.tif,0.2984,536046.9611,5281850.7696,19.8420\n',
'out04-32-44-39.tif,0.311989,536046.6392,5281850.9418,19.8584\n',
'out04-32-44-51.tif,0.346901,536046.3172,5281851.1140,19.8749\n',
'out04-32-44-63.tif,0.358519,536045.9953,5281851.2862,19.8913\n',
'out04-32-44-75.tif,0.342837,536045.6733,5281851.4584,19.9078\n',
'out04-32-44-87.tif,0.32909,536045.3513,5281851.6306,19.9242\n',
'out04-32-44-99.tif,0.294824,536045.0294,5281851.8028,19.9406\n']
Any suggestions greatly appreciated :-)
Based on the code you have written in the comments. This is for python 2.7
fin = open('E:\KGG 375 - GIS Advanced\Assignment 2 - Python\TIR043109gpxpos.txt')
for line in fin: # no need to read these into a list first
info = line.split(',')
blurry = float(info[1])
print info[0],
if blurry > 0.3:
print ' is blurry'
else:
print ' is not blurry'
Explanation:
There is no need to read the lines of a file to a list, you can just iterate over a file and it will read line by line
To be able to compare against a float, you need to convert the 2nd element (info[1]) into a float.
print info[0], will print the filename and the comma will prevent a line break so " is blurry" will print out to the same line. HOX! This is python2.7 syntax so it will not work with python 3.x
I have an interesting issue I am trying to solve and I have taken a good stab at it but need a little help. I have a squishy file that contains some lua code. I am trying to read this file and build a file path out of it. However, depending on where this file was generated from, it may contain some information or it might miss some. Here is an example of the squishy file I need to parse.
Module "foo1"
Module "foo2"
Module "common.command" "common/command.lua"
Module "common.common" "common/common.lua"
Module "common.diagnostics" "common/diagnostics.lua"
Here is the code I have written to read the file and search for the lines containing Module. You will see that there are three different sections or columns to this file. If you look at line 3 you will have "Module" for column1, "common.command" for column2 and "common/command.lua" for column3.
Taking Column3 as an example... if there is data that exists in the 3rd column then I just need to strip the quotes off and grab the data in Column3. In this case it would be common/command.lua. If there is no data in Column3 then I need to get the data out of Column2 and replace the period (.) with a os.path.sep and then tack a .lua extension on the file. Again, using line 3 as an example I would need to pull out common.common and make it common/common.lua.
squishyContent = []
if os.path.isfile(root + os.path.sep + "squishy"):
self.Log("Parsing Squishy")
with open(root + os.path.sep + "squishy") as squishyFile:
lines = squishyFile.readlines()
squishyFile.close()
for line in lines:
if line.startswith("Module "):
path = line.replace('Module "', '').replace('"', '').replace("\n", '').replace(".", "/") + ".lua"
Just need some examples/help in getting through this.
This might sound silly, but the easiest approach is to convert everything you told us about your task to code.
for line in lines:
# if the line doesn't start with "Module ", ignore it
if not line.startswith('Module '):
continue
# As you said, there are 3 columns. They're separated by a blank, so what we're gonna do is split the text into a 3 columns.
line= line.split(' ')
# if there are more than 2 columns, use the 3rd column's text (and remove the quotes "")
if len(line)>2:
line= line[2][1:-1]
# otherwise, ...
else:
line= line[1] # use the 2nd column's text
line= line[1:-1] # remove the quotes ""
line= line.replace('.', os.path.sep) # replace . with /
line+= '.lua' # and add .lua
print line # prove it works.
With a simple problem like this, it's easy to make the program do exactly what you yourself would do if you did the task manually.
