# recursive function
def printUptoN(n):
    #condition for calling
    if n>1:
        printUptoN(n-1)
    print(n, end=" ")
        
# take input of the number upto 
# which numbers will be printed
n=int(input("Enter the upper limit="))

# call the recursive function to 
# print the natural numbers
printUptoN(n)

Output

Case 1:

Enter the upper limit=11

First 11 natural numbers are : 1 2 3 4 5 6 7 8 9 10 11

Case 2:

Enter the upper limit=5

First 5 natural numbers are : 1 2 3 4 5
