Python program to display natural numbers from 1 to n

In this tutorial, we will discuss the Python program to display natural numbers from 1 to n through different 3 ways

In this post, we are going to learn how to print natural number from 1 to entered number in different 3 ways

Python code to display natural numbers Using for loop

This program allows the user to enter a maximum number. and then, it displays natural numbers from 1 to given number using for loop in Python language

Program 1

#print 1 to n natural number
#using for loop
num=int(input("Please enter maxinmum number: "))
print("Natural numbers 1 to ",num )
for i in range(1,num+1):
     print i,

When the above code is executed it produces the following output

Please enter maxinmum number: 12
Natural numbers 1 to 12
1 2 3 4 5 6 7 8 9 10 11 12

Python code to display natural numbers Using while loop

This program allows the user to enter a maximum number. and then,it displays natural numbers from 1 to given number using while loop in Python language

Program 2

#Python program to print natural number fro 1 to n
#using while loop
num=int(input("Enter maximum Natural number: "))
i=1;
while i<=num:
    print(i),
    i=i+1

When the above code is executed it produces the following output

Enter maximum Natural number: 12
1 2 3 4 5 6 7 8 9 10 11 12

 

Python code to  print natural numbers Using function

This program allows the user to enter a maximum number. and then, it displays natural numbers from 1 to given number using the function in Python language

Program 3

#print 1 to n natural number
#using function
num=int(input("Please enter maxinmum number: "))
print("Natural numbers 1 to ",num )

def naturalNum(num):
   for i in range(1,num+1):
     print i,

naturalNum(num)

When the above code is executed it produces the following output

Please enter maxinmum number: 15
Natural numbers 1 to 15
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
