【问题描述】：

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

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

这是终端的结果

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

【参考方案1】：

你需要从functools模块中导入reduce函数。

from functools import reduce

它会起作用的。
