Indentation

You might have noticed that the commands following the if or else statements are indented. This indented code is called a block of code. It's important that when the condition of an if statement is true, it is not just the following line that executes but the indented block of code. For example:

password = "123456"
if password == "123456":
	print("The password is very weak")
	print("Please choose a stronger password")
print("The program will now exit")

Here, if the password equals 123456, the indented block of code is executed. In this case, it prints The password is very weak and Please choose a stronger password. Then, independently of the if statement, it prints The program will now exit.

The same applies to the else statement - if the if condition is false, the indented block of code following the else statement is executed.
