How do I open a DWG file extension with Python?

Question

I have a file with extension .dwg (AutoCAD), and I want to call that file from a Python console and present it on the web. Is there a module for the .dwg extension or some other solution?

Answer 1

GNU LibreDWG (GitHub mirror) is the canonical answer in late 2021. Hilariously forked from the now defunct LibDWG project documented in ^{...wait for it} Esperanto, LibreDWG:

• Optionally installs Python 3 bindings (enabled by default).
• Optionally installs DWG→DXF converters (enabled by default).
• Is unsurprisingly licensed under the GPL 3.0 (fine for web backends; less fine everywhere else).
• Supports almost the entirety of R2010+.

Seriously, it's hot. LibreDWG is the only sane choice that still matters. Let's embrace sanity, everybody.
