Key Topics to Revise

1

Flow of Control and Selective Statements

  • Flow of control means the order of execution of statements in a program.
  • Sequential statements are executed one after the other without any jump.
  • Selective statements are executed depending upon a condition.
2

if, if...else, if-elif-else, and Nested if

  • An if statement runs a block only when the condition is true.
  • An if...else statement has one block for true and one block for false.
  • Else is optional in the if-elif-else construct.
3

While Loop, For Loop, Range, and Membership Operators

  • Iterative statements are repeated depending upon a condition.
  • While loop is a pre-test, conditional loop.
  • For loop is a pre-test, counting loop.
4

Nested While Loop, Break, Continue, and Pass

  • A nested while loop is a while loop inside another while loop.
  • The loop counter variables for the inner and outer loop should be different.
  • In a nested while loop, the inner loop terminates first, then the outer loop terminates.
