step: This optional value defines how much the value should increase or decrease each time.
The default step value is 1, which means the numbers go up one at a time. You can also use a
negative step value to create a descending sequence.

For example: range(10, 2, -2) gives [10, 8, 6, 4].
range(2, 8, 3) gives [2, 5].

FOR LOOP IN PYTHON

The for loop repeats a block of statements a fixed Start
number of times. It is commonly used to go through
(iterate over) a sequence like a list, a string or a range
of numbers. It can be specified using a sequence or a False Loop condition
range of values.

Syntax of the for loop: True decrement

for variable in sequence: Code to be executed

Statement block to be repeated
The for loop variable iterates over the set of values given Stop
in the sequence, repeating the loop body once for each
item. Therefore, the loop header itself defines how many times the loop is going to repeat. For
each iteration, the loop variable takes up the next value from the set and executes the loop body

one more time. The process goes on till the last item of the set has been used.

Syntax of the for loop with the range():

for variable in range(start, stop, step):

Statement block to be repeated
The for loop initialises the variable with the start value. With each iteration, the variable
changes based on the step value—increment or decrement. This continues until it reaches the
stop value (which is not included). The code inside the loop runs once for each value. This makes
it easy to repeat tasks in a clear and controlled way when you know how many times you want
to repeat them.
