[Tutor] getattr help

[mjolewis]

What is the purpose of getattr? Why not just use help or am I completely 
misunderstanding this?

>From what I read, getattr allows you to get a reference to a function without 
>knowing its name until runtime. 

However, the example provided is:

li = ['larry', 'curly]
getattr(li, 'pop')

It seems to me that I need to know the name of the function to use getattr?

Please help.

[Tutor] Opensource projects / Subversion

[mjolewis]

Hey everyone,

I finally made my way into working on Opensource projects. I installed 
tortoisesvn. I included command line tools when running the installer. However 
when I invoke svn at command line, I get the following error:

"svn: command not found"

It seems like svn isn't installed, but again, I had the installer include 
command line tools. 

Please help.

[Tutor] Re.findall()

[mjolewis]

Hi everyone,

I am having trouble understanding re.findall(). I've read through the 
documentation and looked at at some examples online, but I still don't have a 
clear picture. 

I am going through pythonchallenge.com and I am on challenge 3. I've see. The 
answer to the problem, but I don't understand the "pattern" portion of 
re.findall(). 

Thanks!
