Question

Python program. Character-Analysis Program Problem Statement: Design a program - IN PYTHON - that asks the user to enter a string. The string will then be displayed back to the user. This is followed by determining the number of alphabetic characters, numeric characters, lower_case letters, upper_case letters, whitespace characters, and then displaying them. The user should be given additional chances to enter additional strings, and each time a string is entered, the above process is to be performed. The inputting is to stop when the user enters "end" as the input string. At that point, the total number of alphabetic characters, numeric characters, lower_case letters, upper_case letters, whitespace characters are to be displayed and the program terminated. An algorithm: 1. Prompt the user to enter a string at the keyboard 2. As long as the string is not "end" 2.1 Display the string, along with an appropriate message 2.2 Examine the current character of the string 2.2.1 If it's alphabetic, update the alphabetic_counter and the total_alphabetic_counter 2.2.2 If it's numeric, update the numeric _counter and the total_numeric_counter 2.2.3 If it's a lower_case letter, update the lower_case _counter and the total_lower_case_counter 2.2.4 If it's a upper_case letter, update the upper_case _counter and the total_upper_case_counter 2.2.5 If it's a whitespace character, update the whitespace _counter and the total_whitespace_counter 2.2.6 Continue from step 2.2 with the next character until done with this string 2.3 Display the alphabetic_counter, numeric _counter, lower_case _counter, upper_case _counter, and whitespace _counter, each on a separate line, and each along with an appropriate message 2.4 Prompt the user to enter another string at the keyboard 3. Display the total_alphabetic_counter, total_ numeric _counter, total_lower_case _counter, total_ upper_case _counter, and total_ whitespace _counter, each on a separate line, and each along with an appropriate message 4. Stop ================================================================================== NOTE 1: The program will process alphabetic, numeric, and whitespace characters only.

Python Programm :

    alphabets, numeric, lower, upper,space =[],[],[],[],[]

    for letter in string:

        if letter.isupper():

            upper.append(letter)

        elif letter.islower():

            lower.append(letter)

        elif letter.isspace():

            space.append(letter)

    for letter in string:

        if letter.isalpha():

            alphabets.append(letter)

        elif letter.isdigit():

            numeric.append(letter)

    print('Number of alphabetic characters: {}\nAlphabetic characters :{}'.format(len(alphabets),alphabets))

    print('Number of numeric characters : {} \nNumeric characters: {}'.format(len(numeric),numeric))

    print('Number of lower_case letters : {} \nlower_case letters: {}'.format(len(lower),lower))

    print('Number of upper_case letters :{} \nupper_case letters: {}'.format(len(upper),upper))

    print('Number of whitespace characters : {}\nwhitespace characters: {}'.format(len(space),space))

s = input('Please Enter the String: \n')

print('Given sting is :\n {}'.format(s))

String_check(s)

new_s = input('Please provide addition string or "End":')

if new_s != "End" :

    new_s =new_s + s

    print('New string with previous:{}'.format(new_s))

    String_check(new_s)

else:

    print('End')
