How does the Python parser search for module locations

This article mainly introduces the Python parser how to search module location, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let Xiaobian take you to understand.

1. Find the current directory first.

2. If it is not in the current directory, Python will search each directory under the shell variable PYTHONPATH.

3. If it cannot be found, Python will check the default path.

Under UNIX, the default path is generally / user/local/lib/python/.

Store the module search path in the sys.path variable of the system module. Variables include the current directory, PYTHONPATH, and the default directory determined by the installation process.

Example

Import sys print (sys.path) # module search path print (sys.version) print (sys.argv) # parameters when running the program, argv is a list. Thank you for reading this article carefully.
