[英]Call a method from a class on something created by a different method in the same class?
I would like to call a method from a class on something created by another method in the class. 我想从类中的方法调用类中的另一个方法创建的东西。 How would I do this?
我该怎么做?
For example, I've just created a class called call me, and would like to use the result of the subtract
method in the add
method. 例如,我刚刚创建了一个名为call me的类,并想在
add
方法中使用subtract
方法的结果。
class call_me(object):
def __init__(self, x, y):
self.x = 5
self.y = 10
def subtract(self):
difference = self.y - self.x
return difference
def add(self.subtract,second_number):
# code to add the difference returned by subtract to the second number.
How would I add a second number to the difference returned by subtract? 如何将第二个数字加到减法返回的差值中? Is there a way I could pass
difference
to add
? 有什么办法可以
add
difference
吗?
def add(self, second_number):
difference = self.substract()
return difference + second_number
