Counter from collection

Here is a practical example of usage of Counter from the collection module.

The function count_letters counts the letters in a text and count_words counts the words. It’s quite lapalissian.

# how many words we use in a text
from collections import Counter


tx = """This library uses pygame and lets you use some widgets ready to be used in your games.
Installation
If you do not have pygame
pip install pygame
If you want to use pygame 2 with python 3.8 use this
pip install pygame==2.0.0.dev10
Check for more recent version of this. Maybe there is an official version of pygame 2 for python 3.8 or more when you read this.
To install pygame_gui:
pip install pygame_gui
Your first program
Taken from the official documentation, here is how you make a button in  a window. The repository og pygame_gui is here."""


def count_letters(text):
    return Counter(text)


def count_words(text):
    return Counter(text.split())

def show_unsorted(dic_l):
    for x in dic_l:
        print(x, dic_l[x])
    print(dic_l)


def show_sorted(dic_l, reverse=True):
    for x in sorted(dic_l, key=dic_l.get, reverse=reverse):
        print(x, dic_l[x])
    print(dic_l)


dic_l = count_letters(tx)
dic_w = count_words(tx)

[show_sorted(x) for x in (dic_l, dic_w)]
