1. 解决模块找不到问题(ModuleNotFoundError: No module named 'test5')

比如import test5时，找不到test5，如果test5在D:/test目录下，则现在添加到工作目录中，再import相关模块

python 复制代码

import sys

print("path:", sys.path)
sys.path.append("D:/test")
print("path2:", sys.path)

import test5

打印

log 复制代码

path: ['E:\\code\\pythonProject', 'E:\\code\\pythonProject', 'D:\\Program Files\\Python312\\python312.zip', 'D:\\Program Files\\Python312\\DLLs', 'D:\\Program Files\\Python312\\Lib', 'D:\\Program Files\\Python312', 'E:\\code\\pythonProject\\venv', 'E:\\code\\pythonProject\\venv\\Lib\\site-packages']
path2: ['E:\\code\\pythonProject', 'E:\\code\\pythonProject', 'D:\\Program Files\\Python312\\python312.zip', 'D:\\Program Files\\Python312\\DLLs', 'D:\\Program Files\\Python312\\Lib', 'D:\\Program Files\\Python312', 'E:\\code\\pythonProject\\venv', 'E:\\code\\pythonProject\\venv\\Lib\\site-packages', 'D:/test']
