what's the difference of Template.append(...) and Template.prepend(...) in pipes module

2016-09-27 Thread Cpcp Cp 
Template.append(cmd, kind) and Template.prepend(cmd, kind) 
Append a new action at the end.The cmd variable must be a valid bourne shell 
command. The kind variable consists of two letters.

My os is windows 7.But this module is used for POSIX.
So,I don't know the doucement said what's difference of 'Append a new action at 
the end/beginning'.

My English is poor:-),I hope I express clearly what I mean.

A regular expression question

2016-09-28 Thread Cpcp Cp 
Look this

>>> import re
>>> text="asdfnbd]"
>>> m=re.sub("n*?","?",text)
>>> print m
?a?s?d?f?n?b?d?]?

I don't understand the 'non-greedy' pattern.

I think the repl argument should replaces every char in text and outputs 
"".
