Python library download location: By default, the library installed by pip is located at Linux/macOS: ~/.local/lib/python3.x/site-packages, Windows: %APPDATA%\Local\Packages\PythonSoftwareFoundation .Python.3.x_qbz5n2kfra8p0\LocalCache\local-packages\Python3x. In addition, the library will be stored as modules and files in a folder named after the library, and contains a special __init__.py file for identification.
Python library download folder
When you install Python libraries using pip, they are downloaded and placed in a specific folder. By default, this folder is located at:
- Linux and macOS: ~/.local/lib/python3.x/site-packages
- Windows: %APPDATA%\Local\Packages\PythonSoftwareFoundation.Python.3.x_qbz5n2kfra8p0\LocalCache\local-packages\Python3x
Folder Structure
Downloaded libraries will be placed in a folder with the following structure:
-
: Contains the modules and files of the library. - __init__.py: A special file that allows the library to be recognized as a package by Python.
Change download location
If you wish to place the downloaded library in a different folder, you can use pip install --target
option specifies the destination folder. For example:
<code>pip install --target=/path/to/my/custom/folder </code>

In addition to the shebang line, there are many ways to specify a Python interpreter: 1. Use python commands directly from the command line; 2. Use batch files or shell scripts; 3. Use build tools such as Make or CMake; 4. Use task runners such as Invoke. Each method has its advantages and disadvantages, and it is important to choose the method that suits the needs of the project.
