问题
I read about python following PEMDAS that is precedence of multiply is more than division.
I ran the following script
print 6*2/1*2
Thus python should interpret this like 12/2 i.e 6 , since precedence of multiplication is more than division.
But, the answer is 24. Could anyone let me know where the problem is? Thanks!
回答1:
* 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
回答2:
Order of precedence in Python
P
E
M
D Left to right
A
S Left to right
