Raw Python Snippet (WIP)

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

# Suppose the following input is supplied to the program:

# Hello world
# Practice makes perfect
# Then, the output should be:

# HELLO WORLD
# PRACTICE MAKES PERFECT

lst = []

while True:
    x = input()
    if len(x)==0:
        break;
    lst.append(x)

for line in lst:
    print(line.upper())
