Select all lines if occurence for one char in vscode

Question

i'm going straight to the point; First of all i'm trying to select all lines if i find one char in common e.g:

-"activit�"

-"activit�s"

-"actrice"

-"actualisation"

I'd like to select all lines where � is present, then i'd like to make a python script removing all words who have less or more than 5 chars

with open("liste_francais.txt") as mot:
    for a in readlines(mot):
            if len(a)!=5:
                a.replace(a, "")

this is my code atm but its not working, may i get help ? :)

Answer 1

import unidecode #e.g. é -> e
lst=[]
with open("liste_francais.txt") as file:"""opening txt file and getting each item from it"""
    lines=file.readlines()
    for a in lines:
            if len(a)==6:"""\n adds up one char so if u want n chars do n+1"""
                lst.append(a)
textfile = open("a_file.txt", "w")"""new txt file"""
for element in lst:
    element = unidecode.unidecode(element)"""é to e"""
    textfile.write(element.upper()+"\n")"""upper for readibility"""
textfile.close()
