# Python | Program to print numbers from N to 1 (use range() with reverse order)

Here, we will learn how to print numbers in reverse order i.e. how to use range() method in reverse order/ decreasing steps.

Given the value of N and we have to print numbers from N to 1 in Python.

## range() Method

This method is used to iterate a range values.

Simply, we use range(start, stop)

Let’s understand by an example, if we want to iterate any loop till a to b, then range statement will be range(a, b+1).

Iterate in reverse order

To iterate range in reverse order, we use 3 parameters

1. Start – start value
2. Stop – end value
3. Step – Increment/Decrement to the value

Examples:

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 escaping 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 1

```    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 (when the value of n is 1)

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