Python remove anything that is not a letter or number

Question

I\'m having a little trouble with Python regular expressions.

What is a good way to remove all characters in a string that are not letters or numbers?

Thanks

Also you can try to use isalpha and isnumeric methods the following way:

text = 'base, sample test;'
getVals = lambda x: (c for c in text if c.isalpha() or c.isnumeric())
map(lambda word: ' '.join(getVals(word)): text.split(' '))
