Overloading in python
By: Python Documentation Team
This answer on how to overload in python actually applies to all methods, but the question usually comes up first in the context of constructors.
In C++ you’d write
class C {
C() { cout << "No arguments\n"; }
C(int i) { cout << "Argument is " << i << "\n"; }
}
In Python you have to write a single constructor that catches all cases using default arguments. For example:
class C:
def __init__(self, i=None):
if i is None:
print("No arguments")
else:
print("Argument is", i)
This is not entirely equivalent, but close enough in practice.
You could also try a variable-length argument list, e.g.
def __init__(self, *args):
...
The same approach works for all method definitions.
