Those functions take any object that supports the iteration protocol. There’s no need for adding say, len, to every object that needs a len function. I’d argue that is consistent. Sure, multi line lambdas might be nice, but equally you can define functions wherever you need them so it’s not really all that different.

I don’t understand this argument. It’s convenient and more efficient to write, yes. But how is it more consistent to have two different calling conventions? The claim that there’s one way to do something i…

Python gained traction because of Google (Google used it initially then Guido worked for them for a decade+, vs. Matz at Heroku/salesforce) and then because it's the easiest way to use ML libs. That's it. It's slower than Ruby, has worse package management and less consistent syntax but if you want to use Tensorflow, PyTorch, etc..., it's the default.

That's a fairly Silicone Valley focused argument. I don't subscribe to the theory at all that Google closed internal use of Python was instrumental in its adoption. Django was released in 2005 and RoR in 2004. I suspect my journey was similar around then (late 2005), I had used PHP, classic ASP and a little Perl. I was looking for something better, read the tutorials for both Django and RoR. Had a look at what deskto…

How does having a function instead of a method indicate that it's out-of-place? Every Ruby tutorial explains that an exclamation mark means in-place, and this convention is consistent across Ruby libraries, unlike Python.

It's a convention, quite a nice one, but not all libraries are consistent and it does have different meanings too (! is sometimes used for "raise an error instead of returning a boolean"). In the Python case, `list.sort()` operates on the object, so you can kind of expect it to do mutation (but there's no convention / guarantee). Though it only makes sense as a function that the list object itself implements. `sorted…

   "abceghiilou"
