The doc command for os.mkdir is incorrect (at least for posix). It specifies that there is an optional mode keyword, but it's not a keyword argument, see below:
>>> import os
>>> help(os.mkdir)
mkdir(...)
 mkdir(path [, mode=0777])
 
 Create a directory.
>>> os.mkdir("/tmp/1", mode=777) 
Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
TypeError: mkdir() takes no keyword arguments
Suggest the following doc comment change:
mkdir(...)
 mkdir(path [, mode])
 
 Create a directory. Mode defaults to 0777 if not specified.
