In C:
====
for(init;condi;update)
{
	block of code;
}

for loop in Python:
===================
for ==> keyword

for is a loop statement which we can use to define the block/group of actions on individual element of the certain group values/collection etc.

ex: 1 to 100
blockofcode ==> 1
block of code ==> 2

Note:
====
for cannot use on numbers directly.

for in number: ==> error

Syntax:
	for loop-variable in range():
		block of actions

	for loop-variable in collection:
		block of actions

a = 100
b = 123.234
c = [1,2,3,4,5,6]
