Python : Sort Characters By Frequency
Показать описание
Video 83: In this video, we are going to sort the characters by frequency
Given a string, we tackle the task of sorting the given string in decreasing order based on the frequency of its characters. The frequency of a character is defined as the number of times it appears in the string.
To achieve this, we break down the solution into three key steps:
1. Converting a string to a dictionary.
2. Sorting a dictionary based on key-value pairs.
3. Repeating keys based on their values.
We begin by converting the input string into a dictionary, followed by sorting it based on values and then by keys. This ensures that characters with the same frequency are sorted first by their appearance count and then by the character itself. Finally, we repeat each key in the sorted dictionary according to its corresponding value.
For an in-depth understanding of these Python code, please refer to the comprehensive explanatory video.
