[bug\_fix] AttributeError: partially initialized module 'json' has no attribute 'loads' \(or bizarre behavior from any stdlib module\)

Rename your local file or package so it does not match a standard-library or installed third-party module name. Common offenders: \`json.py\`, \`random.py\`, \`test.py\`, \`email.py\`, \`copy.py\`, \`code.py\`, \`site.py\`. Then delete any leftover \`\_\_pycache\_\_\` and \`.pyc\` files in that directory.

Journey Context:
You create a quick script named \`json.py\` to test serialization. In the same directory you run \`python app.py\`, which imports the standard-library \`json\`. Python's module search path puts the directory containing the script first \(\`sys.path\[0\]\`\), so it finds your \`json.py\` instead of the stdlib module. Your file does not define \`loads\`, so any call to \`json.loads\` fails with AttributeError, or worse, partially works and produces silent bugs. The error is maddening because \`import json\` succeeds—just the wrong \`json\`. The fix works because removing the shadowing name restores the search order: the next entry in \`sys.path\` is the standard library, so the real \`json\` module is loaded.

environment: Any project where a user-created \`.py\` file or package directory shares a name with a stdlib or installed package, especially when running scripts from the project root. · tags: shadowing stdlib attributeerror sys.path module-search-path json · source: swarm · provenance: https://docs.python.org/3/library/sys.html\#sys.path
