此代码有什么问题？

Question

This is my part of the code:

import functions
def assign_tasks(operators, requests, current_time):
    sort_requests(requests)
    print(requests)

The error is:

NameError: name 'sort_requests' is not defined

The function module has the following functions:

def sort_requests(requests):
   requests.sort(key=operator.itemgetter(3),reverse=True)
   return requests 
def sort_operators_hours(operators):
   operators.sort(key=operator.itemgetter(4))
   return operators

Answer 1

from functions import sort_requests添加from functions import sort_requests或用sort_requests(requests)替换sort_requests(requests) functions.sort_requests(requests)

Answer 2

First : Check your import statement. Is it function or functions.IT should be the name of your python file name.

Second : your function sort_requests has a return statement. U need to store the returned output.Try this

import functions
def assign_tasks(operators, requests, current_time):
    requests = sort_requests(requests)
    print(requests)
