Am trying to write a python program that will prompt a user to type in a string and it will print the number of punctuation marks in that string. below is what i got so far but its not working properly. I need help fixing this code from string import punctuation def count_punctuations(): my_str = input("Enter a string: ") no_punct =0 for char in my_str: if char in punctuation: no_punct = no_punct + 1 print(no_punct) count_punctuations()
