我有这个程序，我正在尝试使用 json 并查看有哪些人才可用，但是当我尝试运行人才时，我在导入时遇到错误

Question

class DeepwokenBuilder:
    def __init__(self):
        self.active = True

    def start(self):
        while self.active:
            print(" Starting... welcome to the deepwoken talent checker! \n")
            self.questions()

            q = input("Would you like to continue? ")

            if q == "yes " or q == "y":
                continue

            else:

        gale = input("How much galebreath do you have?\n")
        frost = input("How much frostdraw do you have?\n")
        thunder = input('How much thunder do you have?\n')

        attributes = [flame, gale, frost, thunder]

        return attributes

        def controller(self):
            pass


if __name__ == '__main__':
    Db = DeepwokenBuilder()
    Db.start()

人才.py

import json
from Main import DeepwokenBuilder


# make talent logic here ig

with open(r'C:\Users\Zahir\Desktop\DeepwokenBuilder\Deepwoken Builder\Talent_list.json') as f:
    Talent_list = json.load(f)


class Talents:
    def __init__(self):
        self.Talent_list = Talent_list
        self.flamecharm = Talent_list['flamecharm']
        self.galebreath = Talent_list['galebreath']
        self.frostdraw = Talent_list['frostdraw']
        self.thundercall = Talent_list['thundercall']
        self.base = Talent_list['base']


    def display_talents(self):
        db = DeepwokenBuilder()

        attributes = db.questions()
        print(attributes)

        for i, v in self.Talent_list.items():
            attunement = i
            for i, v in v.items():
                talent_name = i
                talent_req = v

                print(f"{talent_name, talent_req}, {attunement} ")
                print(attributes)

                # if attributes < whatever

tt = Talents()
tt.display_talents()

错误：

ImportError: cannot import name 'DeepwokenBuilder' from partially initialized module 'Main' (most likely due to a circular import) (DeepwokenBuilder\Deepwoken Builder\Main.py)

我正在尝试找出为什么会出现错误。

Answer 1

您在导入时遇到问题，因为您的逻辑存在真正的问题：

1. 您创建了两个

   DeepwokenBuilder()

   实例，当您在一个实例中更改某些内容时，其他实例将不会有它。您应该只创建一个

   DeepwokenBuilder()

   并将其作为参数发送给其他类 - 作为

   Talents(db)

   或

   tt.display_talents(db)

2. 创建

   Talents()

   后，您必须在

   Main.py

   中创建

   DeepwokenBuilder

    db = DeepwokenBuilder()
    tt = Talents()
    tt.display_talents(db)
    db.start()

如果您更改它，则不必在

DeepwokenBuilder

中导入

Talents.py

，这可以解决

partially initialized module

的问题
