Python Pastebin for Code Snippets

Python is the language where pasting into chat hurts most, because indentation is syntax. One dropped level in a Slack paste and your function silently means something else, or won't run at all; auto-formatting helpfully 'fixes' a tab into spaces and now the bug you're trying to show is gone. files.link stores your content byte-for-byte — two-space, four-space, tabs, even the mixed indentation you're trying to diagnose — and renders it with Python syntax highlighting on an unlisted link, so the snippet a teammate opens is exactly the snippet you pasted.

That fidelity is the whole point for the things Python developers actually share: a function or class snippet during code review, a full pytest failure block, a multi-frame traceback ending in the real exception, a Jupyter cell exported as text, or a minimal reproduction for a library issue. Tracebacks in particular survive intact — the indented File ".../module.py", line N frames, the caret pointing at the offending token, and the final TypeError/KeyError line all render with their structure preserved and a copy button so the reader can paste it straight back into their environment.

The highlighter handles both Python 2 and Python 3 grammar without you specifying a version, and for output that isn't valid Python (REPL transcripts, mixed log + trace) you can switch the language to plain text and still keep exact whitespace. Privacy is built in the same way as every paste here: the link is an unguessable UUID, the view page is noindex, and signed-in users set a custom expiry (1 hour through permanent) so a reproduction tied to an internal codebase can self-delete.

Anonymous pastes need no signup, cap at 100KB, and clear after 24 hours; an account lifts the cap to 1MB and adds the expiry menu and a dashboard to delete pastes early. For a whole notebook rather than one cell, upload the .ipynb as a file from your dashboard and share the file link instead of pasting. Versus a GitHub Gist (which wants a GitHub account and is public-leaning) or a raw chat code block (which mangles indentation), a noindex link that preserves whitespace and highlights cleanly is the lower-friction choice for sharing Python you don't want reformatted or indexed.
