Here, we will figure out how to print numbers backwards request for example the most effective method to utilize extend() technique in turn around request/diminishing advances.

Given the estimation of N and we need to print numbers from N to 1 in Python.

This strategy is utilized to emphasize a range of esteems.

Essentially, we use range(start, stop)

How about we comprehend by a model, on the off chance that we need to emphasize any circle till a to b, at that point go articulation will be a range(a b+1).

Emphasize backward request

To emphasize go backward request, we utilize 3 parameters

Start – start esteem

Stop – end esteem

Step – Increment/Decrement to the worth

Models:

1) To print numbers from B to A

```
for i in range(B, A-1, -1)
print i
```

2) To print numbers from B to A by getting away one number between

```
for i in range(B, A-1, -2)
print i
```

### Program to print numbers from N to 1 in Python

```
# Python program to print numbers
# from n to 1
# input the value of n
n = int(input("Enter the value of n: "))
# check the input value
if (n<=1):
print "n should be greater than 1"
exit()
# print the value of n
print "value of n: ",n
# print the numbers from n to 1
# message
print "numbers from {0} to {1} are: ".format(n,1)
# loop to print numbers
for i in range(n,0,-1):
print i
```

**Output**

```
Enter the value of n: 10
value of n: 10
numbers from 10 to 1 are:
10
9
8
7
6
5
4
3
2
1
```

**Output 2**

```
Enter the value of n: 1
n should be greater than 1
```
