为什么'pip show json'显示警告

Question

I wrote pip show json , but it shows a warning saying

"WARNING: Package(s) not found: json".

I have already run the program many times with json functions, so I know that it is installed, so why can't I check which version it is? What can I do to check the json version?

Answer 1

The json module is built into Python itself; it isn't separately downloaded, so it has no separate version.

You can verify that multiple ways:

• It's listed at https://docs.python.org/3/library/
• import json; print(json.__file__) import json; print(json.__file__) shows a location that's not under site-packages (where downloaded content goes).
