What is slicing in Python?

Python slice() Function The slice() function returns a slice object. A slice object is used to specify how to slice a sequence. You can specify where to start the slicing, and where to end. You can also specify the step, which allows you to e.g. slice only every other item.

Is Python a palindrome?

Explanation: In the above program, first take input from the user (using input OR raw_input() method) to check for palindrome. Then using slice operation [start:end:step], check whether the string is reversed or not. Here, step value of -1 reverses a string. If yes, it prints a palindrome else, not a palindrome.

What is it called when you reverse numbers?

How do you reverse a string in Python?

Strings can be reversed using slicing. To reverse a string, we simply create a slice that starts with the length of the string, and ends at index 0. The slice statement means start at string length, end at position 0, move with the step -1 (or one step backward).
