# Print Number series without using any loop in Python Program

In this article, we will learn about the solution to the problem statement given below −

## Problem statement

Given Two number N and K, our problem is to subtract a number K from N until number(N) is greater than zero(0), once the N becomes negative or zero then we start adding K to it until that number becomes the original number(N).

**For Example**

N = 10 K = 4

**Output**

10 6 2 -2 2 6 10

## Algorithm

we call the function again and again until N is greater than zero (in every function call we subtract K from N ).

Once the number becomes negative or zero we start adding K in each function call until the number becomes the original number.

Here we used a single function for purpose of addition and subtraction but to switch between addition or subtraction function we used a Boolean type variable flag.

Now let’s observe the implementation in Python

## Example

def PrintNumber(N, Original, K, flag): #print the number print(N, end = " ") #if number become negative if (N <= 0): if(flag==0): flag = 1 else: flag = 0 if (N == Original and (not(flag))): return # if flag is true if (flag == True): PrintNumber(N - K, Original, K, flag) return if (not(flag)): PrintNumber(N + K, Original, K, flag); return N = 10 K = 4 PrintNumber(N, N, K, True)

## Output

10 6 2 -2 2 6 10

Here all variables are declared in global namespace as shown in the image below −

## Conclusion

In this article, we learned about the terminology for printing a number series without using any kind of looping construct in Python 3.x. Or earlier.
