Key Topics to Revise
Introduction to Flow of Control
- Flow of control is the order of execution of statements in a program
- By default, Python executes statements sequentially from top to bottom
- Control structures allow us to change this sequential flow
Selection Statements (if-elif-else)
- if statement executes code block only when condition is True
- if-else provides two alternative paths of execution
- elif allows multiple conditions to be checked in sequence
