Following is a python code snippet I am running on my server. I want to replicate a file 'n' times and save with a different name each time. However, whatever value I give for loop I always end up getting a single replica made.
import os
import time
import shutil
os.chdir(''server_directory)
src='myFile.jpg'
numberofcopies=10
for i in range(0,numberofcopies):
print "replicating {0}".format(i+1)
timestamp=int(round(time.time()))
dst='{0}.jpg'.format(timestamp)
shutil.copy2(src, dst)
Apparently using a timeout in the main thread and running the loop infinitely unless Ctrl-C interruption solved my problem.
import os
import time
import shutil
os.chdir('server_directory')
src='file to replicate.jpg'
i=0
while True:
print "replicating {0}".format(i+1)
timestamp=int(round(time.time()))
dst='{0}.jpg'.format(timestamp)
shutil.copy2(src, dst)
i=i+1
time.sleep(1)
This should replicate my file 5 times with different names.
import os
import shutil
import os
for r in range(5):
original = r'transactions.xlsx'
target = f'Newfile{r}.xlsx'
shutil.copyfile(original, target)
print (f'Action: replicating {original} as {target}')

I transferred some code from IDLE 3.5 (64 bits) to pycharm (Python 2.7). Most of the code is still working, for example I can import WD_LINE_SPACING from docx.enum.text, but for some reason I can't import WD_ALIGN_PARAGRAPH.
At first, nearly non of the imports worked, but after I did
pip install python-docx
instead of
pip install docx
most of the imports worked except for WD_ALIGN_PARAGRAPH.
# works
from __future__ import print_function
import xlrd
import xlwt
import os
import subprocess
from calendar import monthrange
import datetime
from docx import Document
from datetime import datetime
from datetime import date
from docx.enum.text import WD_LINE_SPACING
from docx.shared import Pt
# does not work
from docx.enum.text import WD_ALIGN_PARAGRAPH
I don't get any error messages but Pycharm marks the line as error:
"Cannot find reference 'WD_ALIGN_PARAGRAPH' in 'text.py'".
You can use this instead:
from docx.enum.text import WD_PARAGRAPH_ALIGNMENT
and then substitute WD_PARAGRAPH_ALIGNMENT wherever WD_ALIGN_PARAGRAPH would have appeared before.
The reason this is happening is that the actual enum object is named WD_PARAGRAPH_ALIGNMENT, and a decorator is applied that also allows it to be referenced as WD_ALIGN_PARAGRAPH (which is a little shorter, and possibly clearer). I expect the syntax checker in PyCharm is operating on direct module attributes and doesn't pick up the alias, which is resolved by the Python parser/compiler.
Interestingly, I expect your code would work fine either way. But to get rid of the annoying message you can use the base name.
If someone uses pylint it can be easily suppressed with # pylint: disable=E0611 added at the end of the import line.
I am very new to Python and am trying to append some functionality to an existing Python program. I want to read values from a config INI file like this:
[Admin]
AD1 = 1
AD2 = 2
RSW = 3
When I execute the following code from IDLE, it works as ist should (I already was able to read in values from the file, but deleted this part for a shorter code snippet):
#!/usr/bin/python
import ConfigParser
# buildin python libs
from time import sleep
import sys
def main():
print("Test")
sleep(2)
if __name__ == '__main__':
main()
But the compiled exe quits before printing and waiting 2 seconds. If I comment out the import of ConfigParser, exe runs fine.
This is how I compile into exe:
from distutils.core import setup
import py2exe, sys
sys.argv.append('py2exe')
setup(
options = {'py2exe': {'bundle_files': 1}},
zipfile = None,
console=['Test.py'],
)
What am I doing wrong? Is there maybe another way to read in a configuration in an easy way, if ConfigParser for some reason doesnt work in a compiled exe?
Thanks in advance for your help!
I am running a python script on my raspberry pi, at the end of which I want to call a second python script in the same directory. I call it using the os.system() command as shown in the code snippet below but get import errors. I understand this is because the system interprets the script name as a shell command and needs to be told to run it using python, using the shebang line at the beginning of my second script.
#!/usr/bin/env python
However doing so does not solve the errors
Here is the ending snippet from the first script:
# Time to Predict E
end3 = time.time()
prediction_time = end3-start3
print ("\nPrediction time: ", prediction_time, "seconds")
i = i+1
print (i)
script = '/home/pi/piNN/exampleScript.py'
os.system('"' + script + '"')
and here is the beginning of my second script:
'#!usr/bin/env python'
from __future__ import absolute_import
from __future__ import division
from __future__ import print_function
#from picamera import PiCamera
import argparse
import sys
import time
import numpy as np
import tensorflow as tf
import PIL.Image as Image
Any help is greatly appreciated :)
Since you have not posted the actual errors that you get when you run your code, this is my best guess. First, ensure that exampleScript.py is executable:
chmod +x /home/pi/piNN/exampleScript.py
Second, add a missing leading slash to the shebang in exampleScript.py, i.e. change
'#!usr/bin/env python'
to
'#!/usr/bin/env python'
The setup that you have here is not ideal.
Consider simply importing your other script (make sure they are in the same directory). Importing it will result in the execution of all executable python code inside the script that is not wrapped in if __name__ == "__main__":. While on the topic, should you need to safeguard some code from being executed, place it in there.
I have 2 python file a.py and b.py and I set execute permission for b.py with.
chmod a+x b.py
Below is my sample:
a.py
#!/usr/bin/python
print 'Script a'
import os
script = './b.py'
os.system('"' + script + '"')
b.py
#!/usr/bin/python
print 'Script b'
Execute "python a.py", the result is:
Script a
Script b
I've written one small python script to fix the checksum of L3-4 protocols using scapy. When I'm running the script it is not taking command line argument or may be some other reason it is not generating the fix checksum pcap. I've verified the rdpcap() from scapy command line it is working file using script it is not getting executed. My program is
import sys
import logging
logging.getLogger("scapy").setLevel(1)
try:
from scapy.all import *
except ImportError:
import scapy
if len(sys.argv) != 3:
print "Usage:./ChecksumFixer <input_pcap_file> <output_pcap_file>"
print "Example: ./ChecksumFixer input.pcap output.pcap"
sys.exit(1)
#------------------------Command Line Argument---------------------------------------
input_file = sys.argv[1]
output_file = sys.argv[2]
#------------------------Get The layer and Fix Checksum-------------------------------
def getLayer(p):
for paktype in (scapy.IP, scapy.TCP, scapy.UDP, scapy.ICMP):
try:
p.getlayer(paktype).chksum = None
except: AttributeError
pass
return p
#-----------------------FixPcap in input file and write to output fi`enter code here`le----------------
def fixpcap():
paks = scapy.rdpcap(input_file)
fc = map(getLayer, paks)
scapy.wrpcap(output_file, fc)
The reason your function is not executed is that you're not invoking it. Adding a call to fixpcap() at the end of your script shall fix this issue.
Furthermore, here are a few more corrections & suggestions:
The statement following except Exception: should be indented as well, as follows:
try:
from scapy.all import *
except ImportError:
import scapy
Use argparse to parse command-line arguments.
Wrap your main code in a if __name__ == '__main__': block.
i'm starting to learn Qt and i'm currently doing the alert.pyw example. The example works just fine but i wanted to test it if it really works like it's described so when i pass the time parameter i acctually put in a time to be reached (for example, now it's 11:34 and i passed 11:35 or 11:36, just to be sure i tried a few times with longer waiting times and i actually waited after time it should have popped up for a few minutes).
Well, when the set time is reachead no window actually pop up to "Wake me up".
Is this because the code actually isn't meant to work or there is something weird going on?
Here is the code:
from __future__ import division
from __future__ import print_function
from __future__ import unicode_literals
from future_builtins import *
import sys
import time
from PyQt4.QtCore import (QTime, QTimer, Qt, SIGNAL)
from PyQt4.QtGui import (QApplication, QLabel)
app = QApplication(sys.argv)
try:
due = QTime.currentTime()
message = "Alert!"
if len(sys.argv) < 2:
raise ValueError
hours, mins = sys.argv[1].split(":")
due = QTime(int(hours), int(mins))
if not due.isValid():
raise ValueError
if len(sys.argv) > 2:
message = " ".join(sys.argv[2:])
except ValueError:
message = "Usage: alert.pyw HH:MM [optional message]" # 24hr clock
while QTime.currentTime() < due:
time.sleep(20) # 20 seconds
label = QLabel("<font color=red size=72><b>{0}</b></font>"
.format(message))
label.setWindowFlags(Qt.SplashScreen)
label.show()
QTimer.singleShot(60000, app.quit) # 1 minute
app.exec_()
Thanks for any help
