“功能”对象不可迭代

如何解决“功能”对象不可迭代

当我输入

guest_list = [('Ken',30,"Chef"),("Pat",35,'Lawyer'),('Amanda',25,"Engineer")]

for guests in guest_list:          #guests is a tuple
    
     res = "{} is {} years old and works as {}.".format(guests[0],guests[1],guests[2])
     print(res)

工作正常 但是当我将其更改为

def guest_list(guests):

    for guests in guest_list:

        res = "{} is {} years old and works as {}.".format(guests[0],guests[2])
        print(res)
guest_list([('Ken',"Engineer")]

我明白了

TypeError: 'function' object is not iterable

有人有什么建议吗？

谢谢

解决方法

您正在遍历函数名guest_list而不是列表名guest。 guest_list函数中的代码应如下所示

@Given("^I perform login operation for \"([^\"]*)\" with body$")
    public void iPerformLoginOperationForWithBody(String url,DataTable table) throws Throwable {

        var data = table.raw();

        HashMap<String,String>pathParams = new HashMap<>();
        pathParams.put("emailAddress",data.get(1).get(0));

 _response = RestAssuredExtension.PostOperationWithBodyAndPathParams(url,pathParams);

,

更改：

Uncaught TypeError: Cannot assign to read only property 'exports' of object '#<Object>'
    at Module.<anonymous> (Getters.js:954)

收件人：

import React from 'react';
import { useDispatch,useStore,useSelector } from 'react-redux';
import { selectNavMenuItem } from './ActionCreators';

let Getters = require('./Getters');

function AbstractNavBar( { options,name } ){

  let active = useSelector( state => 
    Getters.getActiveMenuItem( state,name )
  )
  let dispatch = useDispatch();
  let items = options.map(
    item => (
      <li class="nav-item">
      <a id={name+'-'+item.href}
      class={"nav-link" + (item.href === active ? " active " : "")} 
      href="#" 
      onClick={e=>{
    dispatch(selectNavMenuItem( name,item.href ))}}>
      {item.label}
      </a>
      </li>
    )
  )
  return (
    <div class="navbar">
    <ul class="nav nav-pills">
    { items }
    </ul>
    </div>
  )
}

export default AbstractNavBar;

函数名称与def guest_list(guests): 冲突。并且参数必须为def show_guest_list(guest_list): ，而不是guest_list。

然后将其调用为：

guest_list
