how to use 'if i % number == 0:' with multiple numbers?

Question

just a quick question, how would i make it so that instead of just having 1 number (5 in this example) i could have multiple numbers (e.g. 5 or 6 or 7 etc.) or would i just have to do all of them seperately.

This is my example - if (i % 5 == 0):

i know it seems like a dumb question but i can't figure it out for some reason unless it's not possible. I've already tried if (i % 5 or 6 == 0): and if i % (5 or 6) == 0: but neither of them worked.

hope this makes sense thank you in advance

Answer 1

You can use the 'mod' function from numpy, which will return the result as a list. And put the result in the any function, which will return True if at least one value has a remainder after division.

numpy.mod

import numpy as np

i = 10
aaa = np.any(np.mod(i, [1, 2, 3]))
print(aaa)

Output

True

Results the remainder is zero everywhere.

i = 10
aaa = np.any(np.mod(i, [1, 2, 5]))
print(aaa)

Output

False

You can use the RxJs Conditional Operator iff to achieve that if both of your services return an Observable or a Promise.

The iff operator takes 3 arguments, first when being your condition, 2nd and 3rd being your different services that return an Observable/Promise.

If the condition is true subscribe to the first observable, if it is false subscribe to the second observable

 iif(
      () => {
           //Add your condition here
           return a + b === 4;
         },
         this.someService.someMethodWhenTrue(),
         this.someService.someMethodWhenFalse()
     )
     .pipe(takeUntil(this.unsubscribe$))
     .subscribe((items)=> {
         this.someData = items;
     });
