1==1.0 output True

Question

Why print(1==1.0) output True?
The former is int and the latter is float

Answer 1

When you compare values of 2 data types, the interpreter will automatically turn them into 1 type. So the output will always be true.
But on languages like java, js, (and maybe c langs) they use === , equality and type checking

Answer 2

On a deeper level, it depends on how the types, specifically their comparison tools, are designed.

You can't just compare everything in Python, very often you'll get a TypeError when you try.

But for int and float, one cross-class comparison is defined, I guess for convenience.
