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 length of the string is equal to 0, the string is returned. If not equal to 0, the reverse function is recursively called ...
Sample Solution: Python Code: # Define a function named reverse_string that takes one argument, 'str1'.defreverse_string(str1):# Check if the length of the input string 'str1' is divisible by 4 with no remainder.iflen(str1)%4==0:# If the length is divisible by 4, reverse the ch...
Write a Python program to reverse a string. Sample String:"1234abcd" Expected Output:"dcba4321" Sample Solution-1: Python Code: # Define a function named 'string_reverse' that takes a string 'str1' as inputdefstring_reverse(str1):# Initialize an empty string 'rstr1' to store the reve...
前段时间看到letcode上的元音字母字符串反转的题目,今天来研究一下字符串反转的内容。主要有三种方法: 1.切片法(最简洁的一种) #切片法 def reverse1(): s=input("请输入需要反转的内容:") return s[::-1] reverse1() #运行结果 In [23]: def reverse1(): ...

defreverse_string1(s):"""Return a reversed copyof `s`"""returns[::-1]>>>reverse_string1('TURBO')'OBRUT' 新手第一次遇到列表切片时可能很难理解列表切片。 我觉得使用Python的切片功能来反转字符串是一个不错的解决方案,但是对于初学者来说可能很难理解。
reversed_string = my_string[::-1] print(reversed_string) The [::-1] syntax in the above code tells Python to slice the entire string and step backward by -1, which effectively reverses the string. Reversing a String Using the reversed() Function Another way to reverse a string in Pytho...
