可以使用以下方法来实现字符串的反转：
使用切片操作符[::-1]def reverse_string(s): return s[::-1]s = "hello"reversed_s = reverse_string(s)print(reversed_s)def reverse_string(s): reversed_s = "" for char in s: reversed_s = char + reversed_s return reversed_ss = "hello"reversed_s = reverse_string(s)print(reversed_s)def reverse_string(s): if len(s) == 0: return s else: return reverse_string(s[1:]) + s[0]s = "hello"reversed_s = reverse_string(s)print(reversed_s)
