メソッド終了時に「FIN メソッド名」と表示するデコレータ

Last updated at Posted at 2020-02-20
python
def print_fin(func):
    def wrapper(*args, **kwargs):
        output = func(*args, **kwargs)
        print(f'FIN {func.__name__}')
        return output
    return wrapper

使い方:

python
@print_fin
def greet():
    print('Hello!')

greet()
結果
Hello!
FIN greet
