if.py

# We can nest function calls directly
my_number = int(input("Enter a number: "))  

if my_number > 100:
    print(my_number, "is large")

If my_number is smaller than 100 then the expression is false and so if does not trigger and nothing is printed:

Terminal/Command Prompt

python if.py

Enter a number:  42

Enter a number:  128
