range() is function which generate range list in Python syntax :
range(start,stop, step)
range generate the range between start and stop , with step duration
suppose range(1,10) generate 1 to 10 range , here step is 1 by default if it not passed anything for step(last argument), it will increament each by 1
print(list(range(1,10)))
it will print
[1, 2, 3, 4, 5, 6, 7, 8, 9]
lest just check with for loop how it goes with range()
for i in range(1,10):
print(i)
it will print 1 to 9
1
2
3
4
5
6
7
8
9
lets play with step ,
range(1,10,2) i put step is 2 so it increase by 2 for each step
for i in range(1,10,2):
print(i)
so now print is like this
1
3
5
7
9
you can see the each number printed is increase by 3
is that possible we can print the reverse number with range() function ?
Yes it is see below code
for i in range(10,1,-1):
print(i)
it will increment each step by -1 and we provided stat value is 10 so it goes like 10-1=9 , 8... etc
so it will output like this :
10
9
8
7
6
5
4
3
