[Tutor] searching for newlines does not work!

2010-10-23 Thread win...@interchange.ubc.ca 
This is driving me batty!

In the interactive window, I can use string.replace on newlines for some
strings and not for others.

Here is what work for newlines:

b...@bill-laptop:~$ python
Python 2.6.5 (r265:79063, Apr 16 2010, 13:09:56)
[GCC 4.4.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> test=r"a \n b \n c \n"
>>> test.replace(r"\n","***")
'a *** b *** c ***'

Yay! So far, so good. But now I put in a string with newlines, test2, using
the triple quote method :

>>> test2="""
... a
... b
... c
... """
>>> test2.replace(r"\n","***")
'\na\nb\nc\n'
>>> test2
'\na\nb\nc\n'

Boo! It does not work. So there here is my question: Why does test work but
test2 does not? (And: Why me?)

Thanks for any suggestions,

Bill

(Hope this reply makes it back to the Tutor list; I didn't see how the list
would know this is a reply... I'm trying a reply-all)

This is where I say Doh! and Thanks!

I realize now where my fuzzy-headedness come from. I generally use re
expressions. If these were re search strings, the raw would be necessary.
But they aren't re expressions; they are string expressions. So r is as in
wrong, wrong, wrong!

So, I was stuck in re mode, unable to shift out to string mode. (Doh!)

Thank you for steering this lost lamb back into the python fold

Best,

Bill
