In python, why does 0xbin() return False? [duplicate]

Answer 1

You can use the AST module to get the abstract syntax tree of the expression:

>>> import ast
>>> m = ast.parse('0xbin()')
>>> ast.dump(m)
'Module(
    body=[Expr(
               value=Compare(left=Num(n=11),
                             ops=[In()],
                             comparators=[Tuple(elts=[],
                                                ctx=Load())
                                         ]
                            ))])'

See the abstract grammar for how to interpret the expression, but tl;dr: Num(n=11) is the 0xb part, and Tuple(elts=[], ...) hints towards an empty tuple rather than a function call.
