Regular Expression for pattern substitution

[Vibha Tripathi]

It'd be silly to write the code for it if it already
exists somewhere in the Python re or sre library
module:

I need to find and replace all strings in a text file
from a certain pattern to another pattern.

so for example if I see 'this(\D*)that' anywhere in
the file then I'd like to make is 'that(\D*)this'
where the middle part of the strings remains
unmodified.

Any suggestions?

Peace.
Vibha

PS. How do I avoid getting my email ID web-published
for this mailing list.?

re.replace.

I don't think there's any way to avoid it. Except maybe having an alias
email address or a fake one.

re.replace.

There isn't a re.replace; be careful when you reply to newbies.

Fire up the interpreter and write:
'see that man with this woman holding that dog and this cat'

Hrm, thought it had one. Guess it would help if I actually used regular
expression for replacement.
