Question

I am able to do this:

{'class': 'foo'}

But when I do this:

dict(class='foo')

I get:

File "<stdin>", line 1
     {'class':}
             ^
SyntaxError: invalid syntax

Why can’t python use ‘class’ as a **kwarg? It can just as easily use list, int, len… as keyword arguments.

Answer 1

list, int, and len are not keywords, they are normal identifiers. class is a keyword.
