Define a class with a generator which can iterate the numbers, which are divisible by 7, between a given range 0 and n.

divBy7

n = int(input())
divBy7 = [i for i in range(0, n) if (i % 7 == 0)]
print(divBy7)

def divChecker(n):
    for i in range(n):
        if i % 7 == 0:
            value = True
        else:
            value = False
        print(i, value)

divChecker(n)

class Iter:
    def __init__(self):
        pass
        
    def divid(self,n):
        for i in range(0,n):
            if i%7==0:
                print(i)
