Python-转换为Lambda函数

Question

How can I convert the following to a lambda function in Python (v 2.7) ?

def my_func(obj): 
   if obj.type: 
       return obj.name
   else: 
       return obj.type

Answer 1

You would need to use a ternary operator / conditional expression :

lambda obj: obj.name if obj.type else obj.type

Though, it seems you need to flip the things you return - return type only if is truthy:

lambda obj: obj.type if obj.type else obj.name
