In python what __thing__ do I use for ~, kind of like how __add__ is for +?
In python what __thing__ do I use for ~, kind of like how __add__ is for +?
The equivalent of `__add__` for the `~` (bitwise NOT) operator in Python is `__invert__`. Here's a simple example demonstrating its usage:
1 2 3 4 5 6 7 8 9 10 11 12 13 | class MyClass: def __init__(self, value): self.value = value def __invert__(self): return MyClass(~self.value) # Perform bitwise NOT on the value def __repr__(self): return str(self.value) x = MyClass(5) # 5 in binary is 00000101 print(~x) # Output: -6 (because ~5 is -6 in two's complement representation) |
Testing if the previous output contains the string __invert__
: True
Testing if the previous output contains the string __inv__
