Check the length of the input message and if it is greater than 0, then using for loop we calculate the number of occurrences of each character, Character Frequency Write a program that will accept a sequence of characters terminated by a period and will decide whether the string—without the period—is palindrome. You may assume that the input contains only letters and blanks and is at most 80 characters long. The characters in the string should be sorted based on the following conditions. Sort the characters in the string by their frequency of occurrences (the number of times characters have occurred in the string). If the two different characters have the same frequency, these letters should be sorted based on their alphabetical order. Example:29/8/2021 · One of the built-in ways in which you can use Python to count the number of occurrences in a string is using the built-in string .count () method.
