Python Control Structures

Control Structures

• 2 types:

  • Sequential Control Structure

    • Default flow of a program

    • Statements execute one after another, in the order they are written

    • Example:

      • x = 5

      • y = x + 2

      • print (y)

  • Selection (Decision-Making) Control Structure

    • Executes different blocks of code based on conditions

    • Uses logical or relational expressions

    • if, if-else, elif, switch/case

    • Example:

      • x=int(input(“Enter a number “))

      • if x > 0:

        • print(“Positive”)

      • else:

        • print(“Non-Positive”)
