我已经创建了一个代码，在三个不同的函数上迭代字典。
主要功能是这样的：
> def main():
> # initial roster
> brave_roster = { "Austin Riley": "AB: 615, R: 90, H: 168, HR: 38, AVG: 0.273", "Ronald Acuna": "AB: 467, R: 71, H: 124, HR: 15,
> AVG: 0.266", } ```
>
> The Three Functions are as follows: ``` def
> lookup_player(brave_roster, name): name = input("Enter the name of
> the player you want to lookup:\n")
> if name in brave_roster:
>
> print("Here are the", [name], "stats:", brave_roster[name]) else:
> print("That player does not exist.")
>
> def add_player_to_dict(brave_roster, name, stats): name =
> input("Enter the name of the player you want to add:\n")
> if name not in brave_roster:
> stats = input("Please add Matt's stats:\n")
> brave_roster[name] = stats
> brave_roster.update([(name, stats)])
> print("Here's", name,"'s stats:\n")
> for name, stats in brave_roster.items():
> print(name, ':', stats) else:
> print("That player is already on our roster.")
>
> def delete_in_dict(brave_roster, name): name = input("Enter the name
> of the player you want to remove:\n") if name in brave_roster:
> del brave_roster[name] else:
> print("\n uh typo?", name, "does not play for us")
>
> if __name__ == '__main__': print("\t *** Braves Stats! ***\n")
> print("Welcome to My Braves Stats!") brave_roster = {
> "Austin Riley": "AB: 615, R: 90, H: 168, HR: 38, AVG: 0.273",
> "Ronald Acuna": "AB: 467, R: 71, H: 124, HR: 15, AVG: 0.266", }
> choice = input("Please type your choice number:") if (choice == "1"):
> lookup_player(brave_roster) elif (choice == "2"):
> add_player_to_dict(brave_roster) else:
> (choice == "3")
> delete_in_dict(brave_roster) print("\nThanks for using my Braves Stats.")

What am I doing wrong?
Here is the test file:import unittest class TestDictFunctions（unittest.TestCase）：
def test_search_player_success（self）：test_dict = {“Austin Riley”：“AB：615，R：90，H：168，HR：38，AVG：0.273”} actual = test_dict[“Austin Riley”] expected = lookup_player（test_dict，“Austin Riley”）self.assertEqual（actual，expected）
def test_search_player_no_result（self）：test_dict = {“Austin Riley”：“AB：615，R：90，H：168，HR：38，AVG：0.273”} actual =“N/A”expected = lookup_player（test_dict，“罗纳德Acuna”）self.assertEqual（actual，expected）
def test_add_player_sucess（self）：test_dict = {“Austin Riley”：“AB：615，R：90，H：168，HR：38，AVG：0.273”}实际= {“Austin Riley”：“AB：615，R：90，H：168，HR：38，AVG：0.273”，“罗纳德Acuna”：“AB：467，R：71，H：124，HR：15，AVG：0.266”} expected = add_player_to_dict（test_dict，“罗纳德Acuna”，“AB：467，R：7 ``` 1，H：124，HR：15，AVG：0.266英寸）
self.assertEqual(actual, expected)def test_add_player_duplicate（self）：test_dict = {“Austin Riley”：“AB：615，R：90，H：168，HR：38，AVG：0.273”}实际= {“Austin Riley”：“AB：615，R：90，H：168，HR：38，AVG：0.273”，“Austin Riley（2）"：“AB：350，R：20，H：120，HR：5，AVG：0.214”} expected = add_player_to_dict（test_dict，“Austin Riley”，“AB：350，R：20，H：120，HR：5，AVG：0.214”）self.assertEqual（actual，expected）
def test_delete_player_sucess（self）：test_dict = {“Austin Riley”：“AB：615，R：90，H：168，HR：38，AVG：0.273”} expected = {} actual = delete_in_dict（test_dict，“Austin Riley”）self.assertEqual（actual，expected）
def test_delete_word_no_result（self）：test_dict = {“Austin Riley”：“AB：615，R：90，H：168，HR：38，AVG：0.273”} expected = test_dict actual = delete_in_dict（test_dict，“Shohei Ohtani”）self.assertEqual（actual，expected）

您得到的错误是因为测试代码向add_player_to_dict函数传递了三个参数，但函数定义只接受一个参数（brave_roster）。
要修复此错误，您应该修改函数定义以接受附加参数player_name和player_stats，如下所示：
然后，在测试代码中，您可以修改预期变量，以包含新的玩家名称和统计信息：
调用函数时，传递brave_roster、player_name和player_stats参数：
通过这些更改，测试代码应该可以无错误地运行。
另外，请注意，在delete_in_dict函数中，您应该在删除播放器之后添加return brave_roster语句，以便将修改后的字典返回到调用代码。
