You can use the operator module and a dictionary:
Copyimport operator
ops = {
"+": operator.add,
"-": operator.sub,
"*": operator.mul,
"/": operator.div
}
op_char = input('enter a operand')
op_func = ops[op_char]
result = op_func(a, b)

The operator module http://docs.python.org/library/operator.html exposes functions corresponding to practically all Python operators. You can map operator symbols to those functions to retrieve the proper function, then assign it to your op variable and compute op(a, b).

The strange operator precedence of the logical NOT
Depends on the syntax. A unary operator should have a higher precedence than binary operators. You wouldn't want !a && b mean !(a && b), that would be horrifying. For a not token, it depends on the rest of the language. If you have function application like in ML or haskell with spaces, then not should behave like a function. If not is a special case, then I'd stick to whatever Python and C++ do, to not waste any of the "weirdness budget" on such a triviality. But whatever you do, make it consistent with the rest of the language. If you have no precedences and it's always left-to-right, then stick with that. More on reddit.com

June 12, 2024Overriding operators for a subclass
I get the feeling this is an XY problem, but as you stated it I would just add some qualifier to the sort. class Animal: tail_length = None def __lt__(self, other): return (self.sort_priority, self.tail_length) < (other.sort_priority, other.tail_length) class Dog(Animal): sort_priority = 2 def __init__(self, tail_length): super().__init__() self.tail_length = tail_length class Human(Animal): sort_priority = 1 # Human priority is less than Dog priority, so all humans are "less than" dogs. rover = Dog(5) pluto = Dog(10) david = Human() print(rover < pluto) # True print(david < pluto) # True More on reddit.com

For example, if A and C are true but B is false, A and B and C does not evaluate the expression C. When used as a general value and not as a Boolean, the return value of a short-circuit operator is the last evaluated argument. It is possible to assign the result of a comparison or other Boolean expression to a variable. For example, >>> string1, string2, string3 = '', 'Trondheim', 'Hammer Dance' >>> non_null = string1 or string2 or string3 >>> non_null 'Trondheim' Note that in Python, unlike C, assignment inside expressions must be done explicitly with the walrus operator :=. This avoids a common class of problems encountered in C programs: typing = in an expression when == was intended.

All of these operators share something in common -- they are "bitwise" operators. That is, they operate on numbers (normally), but instead of treating that number as if it were a single value, they treat it as if it were a string of bits, written in two's complement binary.
