Python中的管道字符 [英] Pipe character in Python

问题描述

我看到函数调用中使用了竖线"字符(|):

I see a "pipe" character (|) used in a function call:

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

ax|bx中管道的含义是什么?

What is the meaning of the pipe in ax|bx?

推荐答案

它是整数的按位或.例如，如果ax或bx之一或全部为1，则其值为1，否则为0.它还适用于其他整数，例如15 | 128 = 143，即二进制形式的00001111 | 10000000 = 10001111.

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.
