1、打开JUPTER NOTEBOOK，新建一个PYTHON文档。
2、n = input("Please input string: ")print(n)我们首先让用户输入要进行判断的字符串，然后打印出来查看一下。
3、n = input("Please input string: ")is_palidrome = n[::-1]if n == is_palidrome: print("This is a palidrome.")else: print("This is not a palidrome.")我们可以用IF语句来进行判断，判断倒向的是否等于正向的即可。
4、n = input("Please input string: ")if n == n[::-1]: print("This is a palidrome.")else: print("This is not a palidrome.")其实可以简化一下流程。
5、def reverse(n): a = "" for i in n[::-1]: a = a + i return an = input("Please input string: ")a = reverse(n)if n == a: print("This is a palidrome.")else: print("This is not a palidrome.")也可以定义一个新的FUNCTION，然后进行判断。
6、def reverse(n): a = "" for i in range(len(荏鱿胫协n)): a = a + n[len(n)-1-i] return an = input("Please input string: ")a = reverse(n)if n == a: print("This is a palidrome.")else: print("This is not a palidrome.")我们可以利用长度范围不断往回减去范围值，得到反向的字符串。
7、def reverse(n): a = "" for i in range(len(荏鱿胫协n)): a = a + n[len(n)-1-i] return an = input("Please input string: ")a = reverse(n)if n == a: print("This is a palidrome.")else: print("This is not a palidrome.")继续做多种输入来进行判断。
