Chapter 21: Nested if-else Statement
A nested if-else statement refers to placing one if-else statement inside another if-else block.
print('It\'s a game in which you have to guess a number(number may be between 1-20).')number = int(13)g_num = int(input("Enter a number (between 1-20).: "))if g_num==number: print("You won the game.")else: if number>g_num: print("too low.") else: print("too high.")Output 1:It's a game in which you have to guess a number(number may be between 1-20).Enter a number (between 1-20).: 11too low.Output 2:It's a game in which you have to guess a number(number may be between 1-20).Enter a number (between 1-20).: 15too high.Output 3:It's a game in which you have to guess a number(number may be between 1-20).Enter a number (between 1-20).: 13You won the game.
