Python 方法：使用变量作为 object 的参数

Question

I have a object, that can have some types of arguments, like:

myObject.goUp

myObject.goDown

myObject.goLeft

myObject.goRight

I wish to use a variable to specify which object I am using, like:

variable = goUp

myObject.variable

It is possible? Thank in advance!

Answer 1

Maybe this will do the trick:

variable = 'goUp'
callable = getattr(myObject, variable)
callable()

This will throw AttributeError if the method is not found in the object, so be sure to handle that case.

Answer 2

In your question i think you want to say, can we access the method by some other name.

If above is your question then,No we can not use this way because every method that are present in one class have unique name and if want to use that method so we have access by its original name that.

I hope your doubt is now clear.
