Python. Since any argument can be called as a keyword arg, the names of arguments are a part of the API, and renaming them can break user code.
I have written bugs because of this.

def only_positional(a, b, /):
Pass
def only_keyword(*, foo, bar):
passIt makes it so that certain built-ins and native APIs can be properly typed, sure, but positional/keyword interchangeability is arguably a violation of the Zen, too.
That said, I love Python and it's the language that I taught to my daughters first.
The only thing that might trip up beginners in Go is error handling but if they haven't learned any other way of doing it before then they might just accept it for what it is.
For example, the question "how does `x.y()` get evaluated?" has a very complex answer. `x += y` is even more complex.
For a real deep understanding, you'd probably have to jump into the actual computer microchip architecture to learn how computers store memory and do things like pipelining, branch prediction, and caching. Then a primer on Operating Systems (I like "Three Easy Pieces") should fill in the gaps.
On the other hand, stuff like tabs vs spaces - when you would expect this to even come up? Whatever editor they'd use to start coding with, it'll be configured to use one or the other. In fact, these days, unless you get something exotic, it'll be spaces for sure.
And Python has exactly two ways to write a loop: one for conditional looping, and another when you want to iterate over a collection or a range. Is that really too many?
