The reversed sliced string is : ofskeeG Method #2 : Using string slicing The string slicing can be used to perform this particular task, by using “-1” as the third argument in slicing we can make function perform the slicing from rear end hence proving to be a simple solution. # Py...
# Using slicing to reverse a string my_string = 'Hello, World!' 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. ...
my_string = "Python" reversed_string = my_string[::-1] print(reversed_string) # nohtyP Slicing syntax is [start:stop:step]. In this case, both start and stop are omitted, i.e., we go from start all the way to the end, with a step size of -1. As a result, the new string...

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 characters in 'str...
Python Code: # Define a function named 'reverse' that takes an iterable 'itr' as input and returns its reversedefreverse(itr):# Using slicing with [::-1] reverses the input 'itr' and returns the reversed versionreturnitr[::-1]# Initialize a string variable 'str1' with the value '123...
my_list.reverse()print(my_list)# 输出: [5, 4, 3, 2, 1]注意，reverse函数会直接修改原列表，而不是返回一个新的反转后的列表。如果你想要保留原列表，可以使用切片（slicing）操作来创建一个新的反转列表：python复制代码 my_list = [1,2,3,4,5]reversed_list = my_list[::-1]print(reversed_...
python # Original string my_string = "hello" # Reversing the string using slicing reversed_string = my_string[::-1] # Output the reversed string print(reversed_string) # Output: "olleh" And to reverse a tuple, you can convert it to a list, reverse the list, and then convert it ba...
