Problem handling text files with python

I'm trying to make a game of gallows, and for that, I'm picking up lists of words and putting them in .txt format for Python to use in the game.

When picking up a list of names of people, there are some that come with parentheses after the name, and among these, plus some with equal sign between parentheses, for example:

Ana Beatriz (=)

This is due to the site from where I copied the names. He had some pointers, and he could not copy them without them coming together.

So, I created a code for Python to remove these unwanted characters for me:

entrada = open('Pessoas2.txt', 'r') # Cópia da lista de nomes que tenho
saida = open('Pessoas3.txt', 'w')   # Local onde as linhas editadas serão escritas

for linha in entrada:
    l = entrada.readline()
    l = l.replace('(', '').replace(')', '').replace('=', '')
    l = l.rstrip()
    saida.write(l)

entrada.close()
saida.close()

It was apparently okay, the code works. But he takes more things than I want. My original list has 200 names, and the new file only contains 100 names, meaning it simply erases names, and I do not know why. Could you help me?

This happens because the line is being read from the entrada variable, the correct one would be to get it from the linha variable. Your code should look like this:

entrada = open('Pessoas2.txt', 'r')
saida = open('Pessoas3.txt', 'w')

for linha in entrada:
    l = linha.rstrip()
    # substituindo o ")" por um nova linha
    l = l.replace('(', '').replace(')', '\n').replace('=', '') 

    saida.write(l)
entrada.close()
saida.close()

Another way to do this is to use the traslate method when instead of replace .

with open('Pessoas2.txt') as entrada, open('Pessoas3.txt', 'w') as saida:
    for linha in entrada:
        linha = linha.rstrip()
        linha = linha.translate({ ord('('): '', ord('='): '', ord(')'): '\n' })
        saida.write(linha)
