Reverse a String
1 class practiceYln(): #创建一个名叫practiceYln的类 2 def __init__(self, string): #有参构造函数 3 self.string = string
4 def reversedtext(self, string): 5 str(self.string) #转换为字符 6 print (self.string[::-1]) #字符串切片 7 8 b=practiceYln('baby') 9 b.reversedtext('baby')
May we all proceed with wisdom and grace.
