Regular Expressions re.findall()

Question

I have a function which takes a count and a string as input. It should return a list of all words in that string of length count, and greater. Python however doesn't recognise my variable and returns an empty list.

def word_number(count, string):
    return re.findall(r'\w{count,}', string)

How do I pass in the variable 'count' so that the function returns words of count and longer?

Answer 1

You can use printf style formatting:

re.findall(r'\w{%s,}' % count, string)
