Bug in example code of "Scala 3: Scala for Python Developers"

[gverbruggen]

Near the bottom of the document there's this example:

Filtering:

# Python
f = lambda x: x if x > 1 else 1 
x = filter(f, numbers)

// Scala
val x = numbers.filter(_ > 1)

That first line of Python is wrong.

The correct python for the filter is:

f = lambda x: x > 1
x = filter(f, numbers)

And if you want to more closely mirror the Scala example:

x = tuple(filter(lambda x: x > 1, numbers))

Thank you for reporting! Would you be interested in submitting a fix?

The python code may be correct that way, but in my experience not idiomatic. You try to not name lamdas anyway in python, as in most such cases a plain old function then serves you better.

The final example in the issue description using filter I would expect rather written like this:

x = tuple(n for n in numbers if n > 1)

If I can find the source file I may provide a PR.

PS: some important contributing links on https://docs.scala-lang.org/scala3/contribute-to-docs.html seem to not work (one HTTP/404 and two or three github repo screen displays lacking an issues tab where the link from the scala web page had the text issues 😉 )
