Python -PEMDAS中的运算符优先级 [英] Operator precedence in Python -PEMDAS

问题描述

我在PEMDAS之后阅读了有关python的python的知识，即乘除比除法更重要.

I read about python following PEMDAS that is precedence of multiply is more than division.

我运行了以下脚本

print 6*2/1*2

因此python应该将其解释为12/2即6，因为乘法的优先级大于除法.

Thus python should interpret this like 12/2 i.e 6 , since precedence of multiplication is more than division.

但是，答案是24. 谁能让我知道问题出在哪里?谢谢！

But, the answer is 24. Could anyone let me know where the problem is? Thanks!

推荐答案

*具有相同的运算符优先级作为/.同一组中的运算符从左到右求值，因此您的表达式的求值为:

* has the same operator precedence as /. Operators in the same group evaluate left to right, so your expression evaluates as:

6*2 = 12
/ 1 = 12
* 2 = 24
