In the docs for randrange(), it states:

Keyword arguments should not be used because they can be interpreted in unexpected ways. For example randrange(start=100) is interpreted as randrange(0, 100, 1).

If the signature is random.randrange(start, stop[, step]), why doesn’t randrange(start=100) raise an error, since stop is not passed a value?

Why would randrange(start=100) be interpreted as randrange(0, 100, 1)?

I’m not trying to understand the design choice of whoever wrote the code, so much as understanding how it’s even possible. I thought parameters without default values need to be passed arguments or else a TypeError would be raised.
