Quick Notes
pip install From a Git Repository
python -m pip install git+https://github.com/django/django.git@main
pip install From a local dir
pip install -e /path/to/package
-einstalls the package in a way, that you can edit the package, but it requires that the package source stay in the same place (/path/to/packagein this case) forever.
glob通配符获取文件列表
Add this in your python code:
glob.glob("./*.jpg")
获取当前目录下的jpg文件列表
__init__.py的作用
参考链接 https://www.cnblogs.com/lands-ljk/p/5880483.html
__init__.py 文件的作用是将文件夹变为一个Python模块,Python 中的每个模块的包中，都有__init__.py 文件。
通常__init__.py 文件为空，但是我们还可以为它增加其他的功能。我们在导入一个包时，实际上是导入了它的__init__.py文件。这样我们可以在__init__.py文件中批量导入我们所需要的模块，而不再需要一个一个的导入。
当导入模块时，解释器按照sys.path列表中的目录顺序来查找导入文件。
import sys
print(sys.path)
