python3中lambda函数

def make_repeater(n):
    return lambda s:s*n

twice=make_repeater(2)
 
print(twice('wwss'))
 
print(twice(2)) 

 

 

lambda s:s*n
意思是说，s作为参数，返回s*n作为结果
示例中s传入的是wwss，n传入的是2，
所有结果为：wwsswwss

  

结果：

/Users/didi/Documents/pycarm/venv/bin/python /Users/didi/Documents/pycharm_workstation/lambda_test.py
wwsswwss
