Count letters in a text file

Question

I am a beginner python programmer and I am trying to make a program which counts the numbers of letters in a text file. Here is what I\'ve got so far:

import         


        

Answer 1

import sys

def main():
    try:
         fileCountAllLetters = file(sys.argv[1], 'r')
         print "Count all your letters: ", len(fileCountAllLetters.read())
    except IndexError:
         print "You forget add file in argument!"
    except IOError:
         print "File like this not your folder!"

main()

python file.py countlettersfile.txt
