Why can't I use the '|' bitwise operator in this statement? (lemm.ee)

if coin == 25 | 10 | 5:

If I replace the '|' with 'or' the code runs just fine. I'm not sure why I can't use '|' in the same statement.

Doing the following doesn't work either:

if coin == 25 | coin == 10 | coin == 5:

I know bitwise operators can only be used with integers, but other then that is there another difference from logical operators?

Part of the problem is operator precedence - it's ORing together the three numbers, then comparing that to "coin".

5 = 00101
10= 01010
25= 11001
    11111 = 31

It's testing if coin equals 31.

Thank you for breaking it down.

I'm just now sure when it is appropriate to use '|'. If bitwise operators can only be used with integers (and not floats), what's an example where I can use it.
