How can I remove "word:" from a string in Python?

Question

Hi,

I'm wondering how to remove a dynamic word from a string within Python.

It will always have a ":" at the end of the word, and sometimes there's more than one within the string. I'd like to remove all occurrences of "word:".

Thanks! :-)

Answer 1

Use regular expressions.

import re
blah = "word word: monty py: thon"
answer = re.sub(r'\w+:\s?','',blah)
print answer

This will also pull out a single optional space after the colon.

Answer 2

This removes all words which end with a ":":

def RemoveDynamicWords(s):
    L = []
    for word in s.split():
        if not word.endswith(':'):
            L.append(word)
    return ' '.join(L)
print RemoveDynamicWords('word: blah')

or use a generator expression:

print ' '.join(i for i in word.split(' ') if not i.endswith(':'))

Answer 3

[ chunk for chunk in line.split() if not chunk.endswith(":") ]

this will create a list. you can join them up afterwards.
