Python run code every 100th loop item

Question

I have this simple loop in Python that I am using..

for i, numbercode in enumerate(numbercode_list):
    print ("Item : %s" %i )
    driver.close()
    driver = init_driver()

How would I go about just running the last two lines every 100th loop item? Currently it runs them every time.

Answer 1

You can take the modulus of the number and compare to zero. Modulo (% in Python) yields the remainder from the division of the first argument by the second, e.g.

>>> 101 % 100
1

>>> 100 % 100
0

For your example, this could be applied as follows:

for i, numbercode in enumerate(numbercode_list):
    print ("Item : %s" %i )
    if i % 100 == 0:
        driver.close()
        driver = init_driver()
