Decorators for class methods in Python are functions that take a class method and return a modified version of that method. They allow adding additional behavior to the method without changing its source code.
For example, a decorator can be used for logging method calls, checking access rights, or caching results.
An example of a simple decorator for a class method:
class MyClass:
def decorator(func):
def wrapper(self, *args, **kwargs):
print(f"Calling method {func.__name__}")
return func(self, *args, **kwargs)
return wrapper
@decorator
def method(self, x):
return x * 2
obj = MyClass()
print(obj.method(5)) # Will print a message and the result 10
Here, @decorator wraps the method, adding extra output during the call.
