import - Python: Importing modules from parent folder - Stack Overflow hat's wrong with justimport ptdraft.nib Update: It seems that the problem is not related to the module being in a parent directory or anything like that. You need to add the directory that containsptdraftto PYTHONPATH Y...
importsys current_dir=sys.path[0]parent_dir=sys.path[1]print("当前目录:",current_dir)print("父目录:",parent_dir) 1. 2. 3. 4. 5. 6. 7. 在上述代码中,sys.path[0]表示当前脚本所在的目录。sys.path[1]表示该目录的父目录。输出结果如下: 当前目录: /path/to/current_directory 父目录: ...
importsys sys.path.append(parent_dir_path) 1. 2. 3. 步骤4:导入父目录中的模块或者包 现在,你可以使用import语句导入父目录中的模块或者包了。 importparent_modulefromparent_packageimportmodule 1. 2. 4. 示例 下面是一个示例,假设我们有以下的目录结构: ├── parent_directory │ ├── main.py ...
import sys import os # 获取当前脚本的绝对路径 current_dir = os.path.dirname(os.path.abspath(__file__)) # 将父目录添加到sys.path parent_dir = os.path.dirname(current_dir) sys.path.insert(0, parent_dir) # 现在可以导入父目录中的模块了 import my_module 优势 简单直接,适用于大多数情况。
import path: A list of locations (or path entries) that are searched by the path based finder for modules to import. During import, this list of locations usually comes from sys.path, but for subpackages it may also come from the parent package’s __path__ attribute. import 机制是可扩展...
from threading import Thread from multiprocessing.pool import Pool 使用绝对导入方式也会导致一些问题,当我们导入本地目录的模块时,Python经常会找不到相应的库文件而抛出ImportError异常。解决这样的问题最为简单的是将本地目录添加到sys.path列表中去,在pycharm中可以对文件夹右键选择Mark Directory as->Sources Root...
sys.path 也是程序运行时所有模块共享的, 它表示是import 查找的路径, 你可能会认为 sys.path 与working directory 是一样的,但其实不是,sys.path 是由开始运行的文件(入口文件)位置决定的 python xxx.py 与python project/xxx.py 工作目录不同,但是sys.path却相同,都是xxx.py 所在的位置。这样的机制保证了im...
