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?

Thank you. Not sure why in the link the arithmetic in green results in 7.

Not sure why in the link the arithmetic in green results in 7.

Here's the example from the link:

  1 0 0
| 0 1 1
--------
  1 1 1

111 is the binary representation of 7. This also has the equivalent result:

  1 0 0
| 1 1 1
--------
  1 1 1

All it's doing is going through each column of the binary number, and if at least one of them is a 1, the result is a 1. If they're both a 0, the result is a zero. Then you just convert from binary to decimal, so 111 -> 7.
