Definite Iteration

Definite iteration is iteration a fixed number of times, usually looping through some kind of iterable like a list.

Python implements definite iteration using for loops. It consists of three parts:

1. Initialization: A variable is declared and initialized with an initial value.
2. Condition: A condition is checked before each iteration. If the condition is true, the loop continues; otherwise, it terminates.
3. Update: The variable is updated after each iteration.

Here's an example of a for loop:

for i in range(5):
    print("i is currently ", i)

The loop repeats 5 times, each time incrementing i by one - 0,1,2,3,4

Each time through the loop it checks to see if there is still a number left in the range. if there are no numbers remaining in the range the loop terminates

Definition: The range() function in Python is used to generate a sequence of numbers. It returns a range object which represents a sequence of numbers within a specified range. The range object can be used in for loops or converted to other iterable data types like lists. Syntax: range(start, stop, step)

• start: Optional. The number to start the sequence from. If not provided, it defaults to 0.
• stop: Required. The number to stop the sequence at (exclusive). It does not include this number in the sequence.
• step: Optional. The difference between each number in the sequence. If not provided, it defaults to 1.

Example: code: for i in range(0, 10, 2): print(i) output: 0 2 4 6 8 Explanation: In the above example, the range function is used to generate a sequence of numbers from 0 to 10 (exclusive) with a step size of 2. Each number in the sequence is printed using a for loop.
