For instance, if you start the Python interpreter in the directory package/subpackage1 and then do import moduleX, the name of moduleX will just be moduleX, and not package.subpackage1.moduleX. This is because Python adds the current directory to its search path when the interpreter is ...
Relative imports use a module'snameattribute to determine that module's position in the package hierarchy. If the module's name does not contain any package information (e.g. it is set to 'main') then relative imports are resolved as if the module were a top level module, regardless of ...
sys.path.append('module.zip')importfoo,bar#也可以使用zip中目录结构的具体位置sys.path.append('module.zip/lib/python')#windows下的路径不加r开头,会语法错误sys.path.insert(0,r'C:\Users\Administrator\PycharmProjects\a')#至于.egg文件是由setuptools创建的包,这是按照第三方python库和扩展时使用的一种...
#将mymodule模块(目录)所在的目录(如这个py文件的../..)加入到pythonpath中就可以使用from mymodule import *了 1. 2. 3. AI检测代码解析 sys.path.append(os.path.join(os.path.split(os.path.realpath(__file__))[0],"../..")) 1. try: from .mymodule import myclass except Exception: #Im...
ValueError: Attempted relative import in non-package # 翻译:试图在非包中进行相对导入 SystemError: Parent module '' not loaded, cannot perform relative import # 翻译:父模块'xxx'未加载,不能执行相对导入。 既然关于相对导入的报错提示,说明我们在代码中一定用到了相对导入的语法。下面先简单介绍一下相对导...
python import 设置本地路径 import pathlib,前言相比常用的os.path而言,pathlib对于目录路径的操作更简介也更贴近Pythonic。但是它不单纯是为了简化操作,还有更大的用途。pathlib是Python内置库,Python文档给它的定义是:Thepathlibmodule–object-orientedfilesystemp
()# If a zip file is connected to the third input port,# it is unzipped under "./Script Bundle". This directory is added# to sys.path. Therefore, if your zip file contains a Python file# mymodule.py you can import it using:# import mymodule# Return value must be of a sequen...
api import versions ''' 执行结果: ImportError: No module named 'policy' ''' ''' 分析: 此时我们导入versions在versions.py中执行 import policy需要找从sys.path也就是从当前目录找policy.py, 这必然是找不到的 ''' 绝对导入与相对导入总结 代码语言:javascript 代码运行次数:0 运行 AI代码解释 绝对导入...
pathlib 是Python内置库,Python 文档给它的定义是:The pathlib module – object-oriented filesystem paths(面向对象的文件系统路径)。pathlib 提供表示文件系统路径的类,其语义适用于不同的操作系统。 1. pathlib模块下Path类的基本使用 代码语言:txt AI代码解释 ...
