Using if-else Conditionals

You can add an else clause to an if statement to execute a block of statements if the condition is false.

To create an if-else conditional:

• Type:
  
  

  if condition:
  								block1
  else:
    block2
  							

  
  condition is evaluated. If it's true, block1 is executed; otherwise, block2 is executed (Figure 7.13).
  
  

  Figure 7.13. Only one of the blocks in an if-else conditional is executed.

  

  
  block1 and block2 are indented blocks of statements, and condition is a Boolean expression (see “Using Boolean Operators” in Chapter 2).
