我有一段代码，如下：
result = 0
for item in [3, 2, 5]:
result ^= item
print(result)
以上这个 for 循环能不能用一个函数，或一个语句就计算出来？

result

item

for

print result*reduce(operator.mul, [3,2,5])
这样？

reduce(operator.ixor,[3,2,5])

l = [3,2,5]
reduce(lambda x,y:x^y,l)

@zungmou 你需要
from functools import reduce
import operator
