[bug\_fix] ImportError: attempted relative import with no known parent package

Run the module as part of a package instead of as a standalone script: \`python -m package.module\` from the project root \(the directory containing the package folder\). Alternatively replace \`from . import x\` with an absolute import such as \`from package import x\`, or restructure the code so the file is not executed directly with \`python module.py\`.

Journey Context:
You have a project \`myapp/utils/helpers.py\` that contains \`from . import config\`. Running \`python myapp/utils/helpers.py\` crashes with \`ImportError: attempted relative import with no known parent package\`. You try adding \`\_\_init\_\_.py\` files, then \`sys.path\` hacks, then \`if \_\_name\_\_ == '\_\_main\_\_':\` guards, but nothing works. The real issue is that executing a file directly gives it \`\_\_name\_\_ == '\_\_main\_\_'\` and \`\_\_package\_\_ == None\`, so Python cannot determine the parent package for a relative import. When you instead run \`python -m myapp.utils.helpers\` from the repository root, Python sets \`\_\_package\_\_\` correctly, resolves the relative import through the package hierarchy, and the script runs.

environment: Python 3 package/module project where a file inside a package uses \`from . import ...\` and someone runs it directly with \`python path/to/module.py\`. · tags: importerror relative import __main__ __package__ python -m script execution · source: swarm · provenance: https://docs.python.org/3/reference/import.html\#package-relative-imports
