Dunder methods
| Dunder Method | Operation | Example (normal syntax) | Example (dunder call) |
|---|---|---|---|
__getitem__ | Indexing | [1,2,3][0] → 1 | [1,2,3].__getitem__(0) |
__setitem__ | Item assignment | nums[1] = 9 | nums.__setitem__(1, 9) |
__delitem__ | Delete item | del nums[1] | nums.__delitem__(1) |
__len__ | Length | len(nums) | nums.__len__() |
__contains__ | Membership | 2 in [1,2,3] → True | [1,2,3].__contains__(2) |
__add__ | Concatenate | [1,2] + [3,4] → [1,2,3,4] | [1,2].__add__([3,4]) |
__mul__ | Repeat | [1,2]*2 → [1,2,1,2] | [1,2].__mul__(2) |
__iter__ | Iteration | for x in [1,2,3] | it = [1,2,3].__iter__(); next(it) |
__reversed__ | Reverse iteration | reversed([1,2,3]) | [1,2,3].__reversed__() |
__eq__ | Equality | [1,2]==[1,2] → True | [1,2].__eq__([1,2]) |
