Last update on June 12 2025 12:43:20 (UTC/GMT +8 hours)

Display input in upper and lower case.

Write a Python script that takes input from the user and displays that input back in upper and lower cases.

Sample Solution:

Python Code:

# Prompt the user to enter their favorite language and store the input in the variable 'user_input'.
user_input = input("What's your favorite language? ")

# Print the message "My favorite language is" followed by the user's input converted to uppercase.
print("My favorite language is ", user_input.upper())

# Print the message "My favorite language is" followed by the user's input converted to lowercase.
print("My favorite language is ", user_input.lower()) 

Sample Output:

What's your favourite language? english                                                                       
My favourite language is  ENGLISH                                                                             
My favourite language is  english
