Lesson 4 of 19
Conditions
Use if, elif and else to make decisions.
Introduction
Conditional statements let a program choose what to do based on whether an expression is true or false.
Indentation is part of Python syntax, so keep code inside each branch aligned consistently.
Key insight
Use if, elif and else to make decisions.
Example
score = 82
if score >= 80:
print("Great")
else:
print("Keep practicing")This example shows the core conditions idea in a small, runnable program.
