RE: Testing for the first few letters of a string

[Edwin.Madari@VerizonWireless.com]

use re module

import re
template = '^My name is alex'
astring = 'My name is alex, and I like pie'
if re.match(templa te, astring):
print 'Found it'
else: print '%s does not begin with %s' % (astring, template)

good luck.

Subject: Testing for the first few letters of a string



Okay, I have a fix for this problem, but it is messy and I think there might
be a better way. Heres an example:

Lets say I have a string: "My name is alex"

and I have another string "My name is alex, and I like pie".

I want to test to see if just the "My name is alex" part is there. I don't
care about the pie part.
My first instinct was to just create a for loop and test for the string like
this:

n = 0

for x in string1:
if string1[n] == string2[n]
n = n +0
else:
break
and then later testing to see what n was = to and figuring out if it got
through the whole loop. I feel like there should be an easier way to do
this, and probably is. So Does anyone have a suggestion?

Using re.match instead of str.startswith is overkill.

The ^ is redundant.

astring = 'My name is alex, and I like pie'
if re.match(templa te, astring):
print 'Found it'
else: print '%s does not begin with %s' % (astring, template)

Didn't the OP want to match only at the beginning of the string?
