| = bitwise or

|| = boolean or

---

| is a bitwise or, || is a logical or. | operates on binary values whereas || operates on boolean ones.

E.g. 5 | 3 is 0101 OR 0011 which is 0111 which is 7, whereas True || False is True and False || False is False.

| is the bitwise-OR-operator while || is the logical-OR-operator.
