Python是一种面向对象的编程语言。Python中的几乎所有东西都是具有其属性和方法的对象。类就像对象的构造函数,或者是创建对象的“蓝图”。
只需编写变量名称,任何类或类中的任何方法都可以访问在类外部定义的变量。
# defined outside the class' # Variable defined outside the class. outVar = 'outside_class' print("Outside_class1", outVar) ''' Class one ''' class Ctest: print("Outside_class2", outVar) def access_method(self): print("Outside_class3", outVar) # Calling method by creating object uac = Ctest()uac.access_method() ''' Class two ''' class Another_ Ctest_class: print("Outside_class4", outVar) def another_access_method(self): print("Outside_class5", outVar) # Calling method by creating object uaac = Another_ Ctest_class() uaac.another_access_method() The variables that are defined inside the methods can be accessed within that method only by simply using the variable name. # defined inside the method' '''class one''' class Ctest: print() def access_method(self): # Variable defined inside the method. inVar = 'inside_method' print("Inside_method3", inVar) uac = Ctest()uac.access_method() '''class two''' class AnotherCtest: print() def access_method(self): print()uaac = AnotherCtest()uaac.access_method()
