Jonas, this is a Python forum. If we thought Javascript was a beautiful and
well-designed language, we're be on a Javascript forum, complaining about
Python.

Probably. I don't know Javascript very well. It is possible that your
statements about Javascript are as misinformed as your statements about
Python.
In Python, you certainly can do membership testing of a list:
py> alist = ["ab", "cd", "ef", "gh"]
py> "ef" in alist
True
py> "xy" in alist
False
and you can also test for empty lists just as easily:
py> if alist:
... print("not empty")
... else:
... print("empty")
...
not empty
py> blist = []
py> if blist:
... print("not empty")
... else:
... print("empty")
...
empty
