Python 3.8 错误

ImportError: cannot import name 'mydb' from partially initialized module 'connection' 
(most likely due to a circular import) (C:\U
sers\Mark04\Documents\Python tutorial\databasing\connection.py)

当我尝试执行子模块 select.py

import bcrypt;
from connection import mydb

那有一个导入的模块 connection.py

import mysql.connector
mydb = "Success";

我不知道是什么问题。当我从我的模块 connection.py 中删除 import mysql.connector 时没有出现错误，但它没有解决我的问题。

> python -m select

我使用 difflib 并尝试比较两个句子并找出差异。

有点像这样。

我有这段代码，但它不是逐字分析，而是逐字分析。

import difflib

# define original text
# taken from: https://en.wikipedia.org/wiki/Internet_Information_Services
original = ["IIS 8.5 has several improvements related"]

# define modified text
edited = ["It has several improvements related"]

# initiate the Differ object
d = difflib.Differ()

# calculate the difference between the two texts
diff = d.compare(original, edited)

# output the result
print ('\n'.join(diff))
