Pipe character in Python
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
?
Solution 1:
This is also the union set operator
set([1,2]) | set([2,3])
This will result in set([1, 2, 3])
Solution 2:
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.
