Python Program to Count the Number of Words and Characters in a String

def count_words_and_characters(input_string):
    # Split the input string into words using spaces as separators
    words = input_string.split()

    # Count the number of words
    num_words = len(words)

    # Count the number of characters in the input string
    num_characters = len(input_string)

    return num_words, num_characters

def main():
    print("Quick Intro:")
    print("This program counts the number of words and characters in a given string.")

    print("\nProblem Statement:")
    print("You need to find the number of words and characters in a provided string.")

    # Get input string from the user
    input_string = input("\nEnter a string: ")

    # Call the function to count words and characters
    num_words, num_characters = count_words_and_characters(input_string)

    print("\nProgram:")
    print("def count_words_and_characters(input_string):")
    print("    words = input_string.split()")
    print("    num_words = len(words)")
    print("    num_characters = len(input_string)")
    print("    return num_words, num_characters\n")

    print("def main():")
    print("    input_string = input('Enter a string: ')")
    print("    num_words, num_characters = count_words_and_characters(input_string)")
    print("    print('Number of words:', num_words)")
    print("    print('Number of characters:', num_characters)\n")
    print("main()")

    print("\nHow It Works:")
    print("- The program defines a function 'count_words_and_characters' that takes an input string.")
    print("- Inside the function, the input string is split into words using the 'split' method.")
    print("- The number of words is calculated by finding the length of the list of words.")
    print("- The number of characters is calculated using the 'len' function on the input string.")
    print("- The function returns the counts of words and characters.\n")
    print("- In the 'main' function, the user is prompted to input a string.")
    print("- The 'count_words_and_characters' function is called with the input string.")
    print("- The counts of words and characters are then printed.\n")

    print("Input/Output Example:")
    print("Input:")
    print("The quick brown fox jumps over the lazy dog.")
    print("Output:")
    print("Number of words: 9")
    print("Number of characters: 44")
