class和def之间的区别 [英] Differences between `class` and `def`

问题描述

class 和 def 在python中的主要区别是什么？ python中的类可以与django UI（按钮）交互吗？

What is the main difference between class and def in python? Can a class in python interact with django UI (buttons)?

推荐答案

class 用于定义一个类（可以从中实例化对象的模板）。

class is used to define a class (a template from which you can instantiate objects).

def 定义函数或方法。方法就像属于一个类的函数。

def is used to define a function or a method. A method is like a function that belongs to a class.

# function
def double(x):
    return x * 2

# class
class MyClass(object):
    # method
    def myMethod(self):
        print ("Hello, World")

myObject = MyClass()
myObject.myMethod()  # will print "Hello, World"

print(double(5))  # will print 10

对您所提问题的Django部分一无所知。也许应该是一个单独的问题？

No idea about the Django part of your question sorry. Perhaps it should be a separate question?
