A Recursive code which can be used for any filtering process.

Code_practice.py

'''
In the below code, I just took the modulo criteria for the filtering process. 
if res = 0: The so and so person secured more than 80% or can be taken in any other aspect i.e. the work experience in so and so field.. etc etc.. aspects
if res = 1: >70%
if res = 2: >60%
Or the criterias can be taken the other way i.e. 0: 60% - 70%, 1: >=70% - 80%, 2: >80%
The criteria can be choosen based on changing the number than we're performin modulo operation with.

Recursive Operation

Below is the code:
'''
def pass_check(num):
    if num < 1:
        return 1
    else:
        res = num % 3
        if num == 0:
            print(num)
        else:
            pass_check(num - 1)
            print(res, ":", num)

pass_check(100)
