Exercise 9

Write a program that accepts sequence of lines as input and prints the lines after making all characters in the sentence capitalized.

Code

def user_input():
    while True:
        s = input()
        if not s:
            return
        yield s

for line in map(str.upper, user_input()):
    print(line)

ChatGPT Explanation

This code defines a function user_input() that takes no arguments and continuously prompts the user for input until they provide an empty string (by just pressing enter). Each input string provided by the user is then passed to the str.upper() method to convert the string to uppercase and then passed to the print() function to print it out. The map() function applies str.upper() method to each input string.

The while loop in the function user_input() uses the input() function to continuously prompt the user for input and assigns the input string to the variable s.

The if not s: line checks whether the input string is empty or not. If it is empty, the return statement is executed, which terminates the function and the loop stops. If the input string is not empty, it is passed to the yield statement, which returns the input string to the calling code and continues to execute the next iteration of the loop.

The for loop uses the user_input() function to get user input and the map() function to call the str.upper() method on each input string to convert it to uppercase and the print() function to print it out.
