Extending my text file word count ranker and calculator

[snippsat]

f-string can be used in all cases,then avoid rather ugly string like this.

print("A total of " + str(len(wordlist)) + " words can be found inside this text file.")

To make the code work,and look into that function can take arguments.

# word_count.py
from collections import Counter
import re

def word_count(text):
    wordlist = text.split()
    print(f"A total of {len(wordlist)} words can be found inside this text file.")

def rank_words(text):
    words = re.findall('\w+', text)
    top_10 = Counter(words).most_common(10)
    for word,count in top_10:
        print(f'{word:<4} {"-->":^4} {count:>4}')

def file_read():
    with open('alice.txt') as f:
        text = f.read().lower()
        return text

if __name__ == '__main__':
    text = file_read()
    word_count(text)
    rank_words(text)

Can now give a demo on how if __name__ == '__main__': work.
Running word_count.py script now.

Output:
A total of 29465 words can be found inside this text file.
the  -->  1818
and  -->   940
to   -->   809
a    -->   690
of   -->   631
it   -->   610
she  -->   553
i    -->   543
you  -->   481
said -->   462

Now will import the script.

>>> import word_count
>>> # Nothing happens

This is what we want when import code as module.
We don't want it run at import.
Use it like this:

>>> import word_count

>>> text = word_count.file_read()

>>> word_count.word_count(text)
A total of 29465 words can be found inside this text file.

>>> word_count.rank_words(text)
the  -->  1818
and  -->   940
to   -->   809
a    -->   690
of   -->   631
it   -->   610
she  -->   553
i    -->   543
you  -->   481
said -->   462

Now if remove if __name__ == '__main__':.
The code run when import it,in almost all cases this not wanted.

>>> import word_count
A total of 29465 words can be found inside this text file.
the  -->  1818
and  -->   940
to   -->   809
a    -->   690
of   -->   631
it   -->   610
she  -->   553
i    -->   543
you  -->   481
said -->   462
