square = lambda x: x*x print(square(5))
Multiple return
def calc(a, b): return a+b, a*b
- Decorators def decorator(func): def wrapper(*args, *kwargs): print("Before function") return func(args, **kwargs) return wrapper @decorator def greet(name): print(f"Hello {name}")
- Generators
print(f"Hello {self.name}") p = Person("SAGOR") p.greet()
