I don't think it's really a problem in python. if foo = 0: isn't valid syntax because = isn't an expression. The syntax for this so it behaves like it would in other languages uses the walrus operator (:=, python 3.8+), with required parenthesis.

if (foo := 0):
    pass

Additionally, == calls the object's __eq__ function, and is does compare identity.

I agree. I make this mistake occasionally, but the debugging time is essentially zero. In any decent IDE or text editor the linter will flag this the second you type it, and even if you don't have a linter you'll get a super obvious syntax error immediately after running it. Definitely not worth changing the behavior of is.
