order = [] for i in strA: order.append(i) order.reverse() #将列表反转 print ''.join(order) #将list转换成字符串执行结果: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 请输入需要翻转的字符串:abcdeggsdd ddsggedcba2、分别输出字符串中奇数坐标和偶数坐标的字符 最简单的方法是...
# in python you can treat the string as an array by adding [] after it and # the colons inside represent str[start:stop:step] where if step is a negative number # it'll loop through the string backwards return str[::-1] print (FirstReverse(input())) 非常简洁str[::-1]就可以完成...
由于UserString提供与其超类相同的功能str,因此您可以reversed()开箱即用地执行反向迭代: >>> >>> text = ReversibleString("Hello, World!") >>> # Support reverse iteration out of the box >>> for char in reversed(text): ... print(char) ...
print(reverse(s)) Output: The original string is : Geeksforgeeks The reversed string(using recursion) is : skeegrofskeeG Explanation :In the above code, string is passed as an argument to a recursive function to reverse the string. In the function, the base condition is that if the lengt...
