There is no built-instring.reverse()function. However, there is another easy solution. Use Slicing to reverse a String¶ The recommended way is to use slicing. my_string="Python"reversed_string=my_string[::-1]print(reversed_string)# nohtyP ...
2. [::-1] as function The same slice[::-1], and it implements as a function. defreversed_string(val, start=None, stop=None):returnval[start:stop:-1]print(reversed_string("abcdefghijk"))# k j i h g f e d c b aprint(reversed_string("abcdefghijk", -2,4))# j i h g fC...
The easiest and fastest way to reverse a string in Python is to use the slice operator [start:stop:step]. When you pass a step of -1 and omit the start and end values, the slice operator reverses the string. A more verbose, but readable (and slower) version of the string reversal ...
