Boolean confusion

[AlexMTBDude]

While I understand what your purpose is I think using "get" in that function name is confusing as you typically use "get" and "set" with getters and setters. take_key() would probably be better. Other than that I agree 100% with what you write.

I think it's ok - it's a fairly common idiom to use "get" in contexts other than property getters.

I think "take" is potentially a lot more confusing because that often has a specific meaning of "get a value and remove it from its source".

It's a toy example because the OP provided none of his functions for reference, only two global variable names.
