if statement

The statement that runs a block of code only when a condition is true.

An if statement is the most common conditional: it tests a Boolean condition and runs the indented block beneath it only when that condition is True. Add elif for extra cases and else for the fallback.

Example 
temperature = 30
if temperature > 25:
    print("Warm")
else:
    print("Cool")
Output 
Warm

Where this shows up in real Python

If statements guard risky actions, pick between options, and check results throughout every real program.

if / elif / else

  • if condition: — run a block conditionally
  • elif other: — test another case
  • else: — the fallback branch
  • if x and y: — combine conditions
