我在快速修复中找不到它（没有定义reduce）如何修复它

Question

def sumall(nm1, nm2) :
    return nm1 + nm2 

mynumber = [1, 5, 7, 9, 15, 130]
result = reduce(sumall, mynumber)

这就是终端的结果

Traceback (most recent call last):
  File "g:\python\built_in_function6.py", line 25, in <module>
    new_func(sumall, mynumber)
  File "g:\python\built_in_function6.py", line 23, in new_func
    result = reduce(sumall, mynumber)
NameError: name 'reduce' is not defined

Answer 1

您需要从functools模块导入reduce函数

from functools import reduce

它会起作用的
