How do I use if/elif/else condition in python?

[saolasosme]

The if, elif, and else provides a way of performing an action based on whether a condition is true or flase.

The code below shows an example where if, elif, else is used.

# if, elif, else conditions.

username = "operator"
if len(username) < 5:
    print("Username must be at least 5 characters.")
elif len(username) > 15:
    print("Username cannot be greater than 15 characters.")
else: 
    print("Nice Username!")

As the value of username is less than 5 the result is:

$ python main.py
Username must be at least 5 characters.

If we change the username variable to operator, greater than 5 the result would be:

$ python main.py
Nice Username!

If we set the username to a value greater than 15. You would see.

$ python main.py
Username cannot be greater than 15 characters.
