screenchot of input and output 

import string

def count_words(fname):
'''Returns the number of words in a text file'''
pass
#Open the file for reading
#Read the text into one long string
#Close the file
#Remove the punctuation using string.punctuation
#Split the text into a list of words
#Return the number of words

def main():
'''Controls the program'''
filename = "gb.txt"
num_words = count_words(filename)
print("There are", num_words, "words in", filename)

main() #Start execution

1. Complete the function count_words to return the number of words in a text file. The function
is passed a filename but it should work for any file. Do not change the main function. For full
credit, remove the punctuation in the text before splitting it into words. Hint: assume words
are separated by whitespace. Use the string split method to get a list of words. Then the
length of the list is the number of words in the file.
