I needed to see which packages were pulling in six.
Two ways:
- uv tree --package six --invert → quick “who depends on this?” from uv.lock
- uv pip tree --package six --invert --show-version-specifiers → more pipdeptree-style, constraint-aware view from the actual env

Bonus points if it can convert between them.

The strftime method does the opposite of strptime: it converts datetime objects to strings, allowing us to specify the format we'd like to use during that conversion.

Python allows parentheses just about anywhere, but some unnecessary parentheses can increase confusion more than they increase readability.
I just published a new article on the interesting ways that new #Python programmers often use parentheses in Python.

Unnecessary parentheses in Python
Python's ability to use parentheses for grouping can often confuse new Python users into over-using parentheses in ways that they shouldn't be used.

It's interesting that Python 2 ingrained "print statement" into our collective vocabular so deeply that the phrase is still widely used even though print hasn't been a statement since Python 2.

As Chris & Chris note, I *do* LOVE the Python REPL.
If you're in the Python REPL often, play with pyrepl-hacks and let me know what you think.
I'd also love to hear if you have ideas for more commands (or features) to add.
