The problem here is that the 'c' variable is being treated as the literal character 'c', rather than the integer that you want it to be treated as.

Below code should work for you

def find_words(c,s):
    regex = r'\w{'+str(c)+',}'
    return re.findall(regex,s)

So the variable regex is being assigned the regular expression to pass to the findall function. This allows us to treat the c variable as a number and convert it to a string with, the str() function, so that the count is passed correctly as a string.
