What is the difference between reverse and reversed in Python?

reverse() actually reverses the elements in the container. reversed() doesn’t actually reverse anything, it merely returns an object that can be used to iterate over the container’s elements in reverse order. If that’s what you need, it’s often faster than actually reversing the elements.

How do you reverse a number?

Where reverse is a variable representing the reverse of number.Step 1 — Isolate the last digit in number. lastDigit = number % 10. … Step 2 — Append lastDigit to reverse. reverse = (reverse * 10) + lastDigit. … Step 3-Remove last digit from number. number = number / 10. … Iterate this process. while (number > 0)Nov 1, 2016

How do you reverse a string in Python 3?

How do you reverse a string in a while loop?

1) Here i=length of the given string. While loop iterates until the condition i>0 is false, i.e. if the length of the string is zero then cursor terminates the loop. 2) While loop prints the character of the string which is at the index (i-1) until i>0. Then we will get the reverse of a string.

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).
