Python Program to Print Natural Numbers ( 3 Best Ways )

In this Python examples tutorial, you will learn how to print natural numbers in Python. In this guide, we will see various ways to write a python program to print naturals numbers.

If you are a beginner python programmer, then this example will very helpful for you.

Before writing a python program to print natural numbers, we will see what actually is a natural number?

What is natural number?

A natural number is an integer greater than 0. Natural numbers begin at 1 and increment to infinity. For example: 1, 2, 3, 4, 5, etc.

Python program to print natural numbers

In this example, we will see several ways to print natural numbers.

Python program to print natural numbers using for loop:

In this example, we will print natural numbers up to n terms. Basically, we will ask numbers from the user to print natural numbers up to that number. Here we have used python for loop to print natural numbers.

#ask number from the user
n = int(input("Enter any positive number:- "))
print("Natural number from 1 to {0} are:-".format(n))

#print natural number using for loop.
for i in range(1, n + 1):
	print(i, end=" ")

Output

Enter any positive number:- 12
Natural number from 1 to 12 are:- 1 2 3 4 5 6 7 8 9 10 11 12

Python program to print natural numbers using function:

In this example, we will use the python function to print the natural numbers up to n terms.

#ask number from the user
num = int(input("Enter any positive number:- "))
print("Natural number from 1 to {0} are:-".format(num))

#Custom function to print natural numbers
def naturalNumber(n):
    #print natural number using for loop.
    for i in range(1, n + 1):
        print(i, end=" ")
 
# Call the function 
naturalNumber(num)

Output

Natural number from 1 to 20 are:-
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

Python program to print natural numbers using while loop:

Here we have used python while loop to print natural numbers upto n terms.

#ask number from the user
n = int(input("Enter any positive number:- "))
print("Natural number from 1 to {0} are:-".format(n))
i = 1

#While loop to print natural numbers
while (i <= n ):
	print(i, end=" ")
	i = i + 1

Output

Enter any positive number:- 10
Natural number from 1 to 10 are:-
1 2 3 4 5 6 7 8 9 10
