range in python
#this is the range() function
for a in range(7,1,-2): # range(start, stop, step)
#here 7 is maximum possible number
print(a, end=", ") #1 is minimum possible number but won't be included
# -2 is common diffrence between them
output:
7, 5, 3,

When you call range() with three arguments, you can choose not only
where the series of numbers will start and stop but also how big the
difference will be between one number and the next.
range(start, stop, step)
If your 'step' is negative and 'start' is bigger than 'stop', then
you move through a series of decreasing numbers.
for i in range(10,0,-1):
print(i, end=' ')
# Output: 10 9 8 7 6 5 4 3 2 1range function in python

for a in range(5,-9,-1):
print(a,end=',')
output:

range(4) # [0, 1, 2, 3] 0 through 4, excluding 4
range(1, 4) # [1, 2, 3] 1 through 4, excluding 4
range(1, 10, 2) # [1, 3, 5, 7, 9] 1 through 10, counting by 2srange python 3
# range(start, stop, step)
# start = index to begin at (INCLUSIVE)
# stop = generate numbers up to, but not including this number (EXCLUSIVE)
# step = (can be omitted) difference between each number in the sequence

# range(stop)
for i in range(len(arr)):
print(arr[i]) # prints: 19, 5, 3, 22, 13
