Python Program to Print Numbers in a Range (1,upper) Without Using any Loops

When it is required to print the numbers in a given range without using any loop, a method is defined, that keeps displays numbers from higher range by uniformly decrementing it by one after every print statement.

Below is the demonstration of the same −

Example

 Live Demo

def print_nums(upper_num):
   if(upper_num>0):
      print_nums(upper_num-1)
      print(upper_num)

upper_lim = 6
print("The upper limit is :")
print(upper_lim)
print("The numbers are :")
print_nums(upper_lim)

Output

The upper limit is :
6
The numbers are :
1
2
3
4
5
6

Explanation

• A method named ‘print_nums’ is defined.

• It checks if the upper limit is greater than 0.

• If so, keeps displaying the elements.

• After every display, the upper range value is decremented by 1.

• Outside the function, a value for upper limit is defined.

• This method is called by passing the parameter.

• The output is displayed on the console.
