That's the typical sort of description you get from someone who mostly understands Python's semantics, but is hung up on the idea that everything is either call-by-value or call-by-reference, and is trying to figure out which box Python fits into.
Or they may have read the definition of "call by value" in the Algol60 report, which says that "The actual parameter expression is evaluated and the result is assigned to the formal parameter." Which is exactly what Python does... (Notably, that definition doesn't contain the word "value" at all. So people who argue about the meaning of "call by value" based on the meaning of "value" are barking in the wrong direction.) -- Greg -- https://mail.python.org/mailman/listinfo/python-list
