Question

I have a php script that I called in command line like that :

$php importTextFile.php --user "X" --title "name" notice_X.txt 

I want to use that file in a python script. I’ve tried :

for file in os.listdir("."):
    subprocess.call(["php", "-f", "importTextFile.php"], "--user=X", "--title="'%s' % name, file)

I’ve got he following error :

  File "./pageFromFile.py", line 21, in main
    subprocess.call(["php", "-f","importTextFile.php"], "--user=Bot", "--title="'%s' % nom, fichier)
  File "/usr/lib/python2.7/subprocess.py", line 493, in call
    return Popen(*popenargs, **kwargs).wait()
  File "/usr/lib/python2.7/subprocess.py", line 629, in __init__
    raise TypeError("bufsize must be an integer")
TypeError: bufsize must be an integer

I don’t understand how to fix this error.
Thanks for your help.

edit1 : thanks it works, but I’ve got problem withs args because the Usage message appeared :

Usage: php [options] [-f] <file> [--] [args...]
       php [options] -r <code> [--] [args...]
       php [options] [-B <begin_code>] -R <code> [-E <end_code>] [--] [args...]
       php [options] [-B <begin_code>] -F <file> [-E <end_code>] [--] [args...]
       php [options] -- [args...]
       php [options] -a

edit2 : I’ve changed arguments’s order and it works :
[“php”, “php /script /path”, “-f”, “–user”, “X”, “–title”, X, file ]

Here’s a messy explanation due to messy documentation.

From: http://docs.python.org/library/subprocess.html#frequently-used-arguments

To support a wide variety of use cases, the Popen constructor (and the
convenience functions) accept a large number of optional arguments.
For most typical use cases, many of these arguments can be safely left
at their default values. The arguments that are most commonly needed
are:

From: http://docs.python.org/library/subprocess.html#subprocess.call

The signature for call() is:

subprocess.call(args, *, stdin=None, stdout=None, stderr=None, shell=False)

You’ll want your CL arguments all within a single list – as Jakob provided. That is the first argument to call().

The other positional arguments correspond to initialization parameters for class subprocess.Popen (http://docs.python.org/library/subprocess.html#subprocess.Popen). bufsize happens to be one of them.
