[英]How to use functions between classes in python
If I have more than one class in a python script, how do I call a function from the first class in the second class? 如果我在python脚本中有多个类,该如何从第二个类的第一个类调用函数?
Here is an Example: 这是一个例子:
Class class1():
def function1():
blah blah blah
Class class2():
*How do I call function1 to here from class1*
Functions in classes are also known as methods, and they are invoked on objects. 类中的函数也称为方法,它们是在对象上调用的。 The way to call a method in class1 from class2 is to have an instance of class1:
从class2调用class1中的方法的方法是拥有class1的实例:
class Class2(object):
def __init__(self):
self.c1 = Class1()
self.c1.function1()
The cleanest way is probably through inheritance: 最干净的方法可能是通过继承:
class Base(object):
def function1(self):
# blah blah blah
class Class1(Base):
def a_method(self):
self.function1() # works
class Class2(Base):
def some_method(self):
self.function1() # works
c1 = Class1()
c1.function1() # works
c2 = Class2()
c2.function1() # works
