(I don't know what you mean here by “the same”; the same as what?)
The above creates a new function, which expects no parameters (because
there are no parameters before its ‘:’).
The function, when called, will return the value of the expression
‘update_label2('A', 100)’.
> It looks as though it'd be passing the same two parameters to the same
> function...
Yes, it looks that way, and that's what it does. The parameters are
fixed in the expression and will be the same each time the new function
is called.
> lambda: 'A', 100: update_label2()
This is a syntax error.
Have you tried experimenting with these? Carefully read the reference
material on the ‘lambda’ syntax, and create some functions and
experiment with them.
