FOR loop in python

in loops concept For loop plays major role

range is inbuilt function which is having 3 integers values
range(start,stop,step)
start---from where to start the iteration
stop---upto which value(max value) to execute
step---how much increment is looking for each iteration


example 1:

for x in range(1,10):
    print(x)

out put:
1
2
3
4
5
6
7
8
9



example 2:

for x in range(1,10):

    print("*")

output:
*

nested for loop

for x in range(1,5):
    for y in range (1,5):

          print("*")

output:
