New description:
The write() function does return nothing in Py2
{{{
>>> sys.version
'2.7.5+ (default, Feb 27 2014, 19:37:08) \n[GCC 4.8.1]'
>>> with open("tracked", "w") as f: f.write("boo")
...
>>>
}}}
while in Py3 it returns the number of bytes written
{{{
>>> sys.version
'3.3.2+ (default, Feb 28 2014, 00:52:16) \n[GCC 4.8.1]'
>>> with open("tracked", "w") as f: f.write("boo")
...
3
>>>
}}}
This can be unified by adding something like {{{ignore =}}}
{{{
>>> sys.version
'3.3.2+ (default, Feb 28 2014, 00:52:16) \n[GCC 4.8.1]'
>>> with open("tracked", "w") as f: ignore = f.write("boo")
...
>>>
}}}
About 79 py module are effected.
