    Study Notes

    Loops in Python

    • A while loop is a repeated process that continues until a conditional becomes false.

    Key Elements of a While Loop

    • To solve problems using a while loop, three values need to be identified:
      • Initialization: The starting value of the loop variable.
      • Condition: The conditional statement that is checked at the beginning of each iteration.
      • Increment/Decrement: The operation that updates the loop variable after each iteration.

    Range Function

    • The default starting value for the range() function in Python is 0.
    • When using the range() function, the starting value, stopping value, and step value need to be declared.

    Types of Loops

    • Python supports two different types of loops:
      • While loops: Used for conditional repetition.
      • For loops: Used for iterative repetition.
