Pipe character in Python

Question

I see a "pipe" character (

|

) used in a function call:

res = c1.create(go, come, swim, "", startTime, endTime, "OK", ax|bx)

What is the meaning of the pipe in

ax|bx

?

Answer 1

It is a bitwise OR of integers. For example, if one or both of ax or bx are 1, this evaluates to 1, otherwise to 0. It also works on other integers, for example 15 | 128 = 143, i.e. 00001111 | 10000000 = 10001111 in binary.
