![Subprocess Cp Returns Error - Bufsize Must Be Integer [Duplicate]](https://docuprint.cloud68.co/uploads/subprocess-cp-returns-error-bufsize-must-be_1200.jpg)
I'm trying to copy from one directory to another, and rename them at the same time by calling 'cp' like so:
directories = ['/Users/Me/Folder1/File1.txt', '/Users/Me/Folder/File2.txt']
output = ['/Users/Me/Folder2/Hello.txt', 'Users/Me/Folder2/World.txt']
for in, out, in zip(directories, output):
subprocess.call('cp', in, out)
But it returns:
File "./test.py", line 33, in <module>
subprocess.call('cp', in, out)
File "/usr/local/Cellar/python/2.7.10_2/Frameworks/", line 522, in call
return Popen(*popenargs, **kwargs).wait()
File "/usr/local/Cellar/python/2.7.10_2/Frameworks/", line 659, in __init__
raise TypeError("bufsize must be an integer")
TypeError: bufsize must be an integer
What am I doing wrong?

You've got two problems:
1 - subprocess.call() expects a list of arguments, not multiple arguments:
#wrong
subprocess.call('cp', in, out)
#right
subprocess.call(['cp', in, out])
2 - in is a python reserved keyword, change it to something like inp:
#wrong
subprocess.call(['cp', in, out])
#right
subprocess.call(['cp', inp, out])
