We can use relative imports to import modules from packages that are in the same directory or a subdirectory of the current module. Relative imports are specified using the.(dot) notation to indicate the positio
例如,假设我们有以下文件夹结构: my_folder/|-main.py|-folder1/|-module1.py|-folder2/|-module2.py Python Copy 如果我们想在main.py文件中同时导入module1.py和module2.py的内容,我们可以按照以下方式导入: fromfolder1importmodule1fromfolder2importmodule2 Python Copy 这样,我们就可以在main.py文件中使...
You need three import statements in order to move all the text files to an archive directory. Python’s pathlib provides a Path class that works the same way on different operating systems. Instead of importing different modules such as glob, os, and shutil, you can perform the same tasks ...

It is possible to have a file calledspam.pyc(orspam.pyowhen-Ois used) without a filespam.pyfor the same module. This can be used to distribute a library of Python code in a form that is moderately hard to reverse engineer. The modulecompileallcan create.pycfiles (or.pyofiles when-Ois...
