Question

I am newbie to python. I have an array of words and each word has to be checked to see whether it contains any special characters or digits. If it contains so then i have to skip that word. How should i do this?

Answer 1

My reading of the problem is that you want to discard any words that contain non-alphabetical characters. Try the following:

>>> array = ['hello', 'hello2', '?hello', '?hello2']
>>> filtered = filter(str.isalpha, array)
>>> print filtered
['hello']

You could also write it as a list comprehension:

>>> filtered = [word for word in array if word.isalpha()]
>>> print filtered
['hello']
