The code is not indented - indentation

a program to display the numbers indivisible by 5 but not 7
for i in range(2000,3201):
if i%5!=0 and i%7==0:
print i
else:
continue
Identationerror: unindent does not match any outer indentation level
specifically on line 5, the else statement

Try something like this:
for i in range(2000,3201):
if i%5!=0 and i%7==0:
print i
else:
continue

How to I shorten this code to comply with the DRY (Don't Repeat Yourself) principle?

I want to take words a user provides, store them in a list, and then modify those words so that every other letter is capitalized. I have working code but it is repetitive. I cannot for the life of me figure out how to get all the words ran through in one function and not have it output one long string with the spaces removed. Any help is appreciated.
This is my current code:
def sarcastic_caps(lis1):
list=[]
index=0
for ltr in lis1[0]:
if index % 2 == 0:
list.append(ltr.upper())
else:
list.append(ltr.lower())
index=index+1
return ''.join(list)
final_list.append(sarcastic_caps(lis1))
Imagine 4 more iterations of this ^. I would like to do it all in one function if possible?
I have tried expanding the list index but that returns all of the letters smashed together, not individual words. That is because of the .join but I need that to get all of the letters back together after running them through the .upper/.lower.
I am trying to go from ['hat', 'cat', 'fat'] to ['HaT', 'CaT', 'FaT'].

Regex in python trouble

I have a text file that I would like to search through it to see how many of a certain word is in it. I'm getting the wrong count for the words.
File is here
code:
import re
with open('SysLog.txt', 'rt') as myfile:
for line in myfile:
m = re.search('guest', line, re.M|re.I)
if m is not None:
m.group(0)
print( "Found it.")
print('Found',len(m.group()), m.group(),'s')
break
for line in myfile:
n = re.search('Worm', line)
if n is not None:
n.group(0)
print("\n\tNext Match.")
print('Found', len(n.group()), n.group(), 's')
break
for line in myfile:
o = re.search('anonymous', line)
if o is not None:
o.group(0)
print("\n\tNext Match.")
print('Found', len(o.group()), o.group(), 's')
break
There is no need to use a regex, you can use str.count() to make the process much more simple:
with open('SysLog.txt', 'rt') as myfile:
text = myfile.read()
for word in ('guest', 'Worm', 'anonymous'):
print("\n\tNext Match.")
print('Found', text.count(word), word, 's')
To test this, I downloaded the file and ran the code above, and got the output:
Next Match.
Found 4 guest s
Next Match.
Found 91 Worm s
Next Match.
Found 18 anonymous s
which is correct if you do a find on the document in a text editor!
*As a sidenote, I'm not sure why you want to print a tab (\t) before 'Next Match' each time as it just looks weird in the output but it doesn't matter :)
There are multiple problems with your code:
re.search will only give you the first match, if any; this does not have to be a problem, though, as it seems like the word is only expected to appear once per line; otherwise, use re.findall
the line n.group(0) does not do anything without an assignment
len(n.group()) does not give you the number of matches, but the length of the matched string
you break after the first line in the file
myfile is an iterator, so once the first for line in myfile loop has finished, the other two won't have any lines left to loop (it will never finish because of the break anyway, though)
as already noted, you do not need regular expression at all
One (among many) possible ways of doing this would be this (not tested):
counts = {"worm": 0, "guest": 0, "anonymous": 0}
for line in myfile:
for word in counts:
if word in line:
counts[word] += 1

in python, write a function called wordendwithS() , to count the number of words ending with 's' from the TEXT FILE "file.txt"

I have already tried
def wordendwithS():
f=open("file.txt",'r')
a=f.readlines()
c=0
for i in a:
if i.endswith('s'):
c=c+1
I dont know what to do please help
What is wrong in this?
You have a few problems with your code. The first is that you're not returning the count c which means that your function is doing nothing. Additionally, you are checking if a line ends with 's' instead of if a word ends with 's'. Third, you are not closing your file. You can do this to fix all three of these problems
def wordendwithS():
c = 0
with open('file.txt', 'r') as f:
for l in f:
for i in l.split():
if i.endswith('s'):
c += 1
return c
with is a content manager which autocloses the file after you're done using it.

How do I print specific lines of a file in python?

I'm trying to print everything in a file with python. But, whenever I use python's built-in readfile() function it only print the first line of my text file. Here's my code:
File = open("test.txt", 'r', 0)
line = File.readline()[:]
print line
and thank you for everyone that answers
and to make my question clearer every time I run the code it prints only "word list food
Is this what you are looking for?
printline = 6
lineCounter = 0
with open('anyTxtFile.txt','r') as f:
for line in f:
lineCounter += 1
if lineCounter == printline:
print(line, end='')
Opens text file, in working directory, and prints printLine
File.readlines()
will, as emre. said, return a list of all the lines in your file. If you'd like to produce a similar result using the readline() command,
s=File.readline()
while s!="":
print s
s=File.readline()
Both methods above leave a newline at the end of each string, except for the last string.
Another alternative would be:
for s in File:
print s
To search for a specific string, or a specific line number, I'd say the first method is best. Looking for a specific line number would be as simple as:
File.readlines()[i]
Where i is the line number you are interested in accessing. Looking for a string is a bit more work, but looping through the list would not be too challenging. Something like:
L=File.readlines()
s="yourStringHere"
i=0
while i<len(L):
if L[i].find(s)!=-1:
break
i+=1
print i
would give you the line number that contained the string you were looking for.
Make it more pythonic.
print_line = 6
with open('input_txt_file.txt', 'r') as f:
for i, line in enumerate(f):
if i == print_line:
print(line, end='')
break

printing two things upon a condition match in sml

if (1=1)
then print "sdfsdfs" and print "sdfsdfsdfsdf"
else print "sdfsdf";
This gives an error. I want to do two things if the condition matches. How can I do that?
Parenthesize the commands and separate them with a semicolon:
if 1=1
then (print "sdfsdfs"; print "sdfsdfsdfsdf")
else print "sdfsdf"
