['Memria', 'f¡sica', 'available', '5.277', 'MB'']

['Mem ria', 'Virtual:', 'Available:', '6.094', 'MB']
['Mem ria', 'Virtual:', 'Em', 'Use:', '3.174', 'MB']

archive_sysinfo = open('saida_systeminfo.txt', 'r')
text_sysinfo = archive_sysinfo.readlines()
lista_linhas2 = []
lista_info = []

for linha2 in text_sysinfo:
    lista_linhas2.append(linha2.split())

for linha2 in lista_linhas2:
    if "Mem¢ria" in linha2:
        lista_info.append(linha2[0:6])
        print(linha2[0:6])

Answer 1

Since you want to copy part of one file to another, the steps I would do are:

1. Open a file for reading (open('meu_arquivo', 'r'))
2. Open a file for recording (open('outro_arquivo', 'w'))
3. Read the file line by line for linha in arquivo:
4. Test if the line being read should be copied (in this case I used the str.startswith())
5. Write the line in the output file (View file-Objects methods).

I advise you to open files with the with, this way it takes care of closing the file at the end of the reading or in case of an error occurs.

Below an example running:

with open('saida_systeminfo.txt', 'r') as info, \
     open('resultado.txt', 'w') as txt:
    for line in info:
        if line.startswith('Memória'):
            txt.write(line)

^{Repl.it with the code working}

Edit

Since the contents of the file that AP posted contains some errors of encoding, I’ll just point out that the function open() has an optional parameter encoding where you can use one of encodings python-supported. Examples:

arquivo = open('meu_arquivo.txt', 'r', encoding='utf_8')
arquivo = open('meu_arquivo.txt', 'r', encoding='utf8')  # alias de 'utf_8'
arquivo = open('meu_arquivo.txt', 'r', encoding='UTF')  # alias de 'utf_8'

arquivo = open('meu_arquivo.txt', 'r', encoding='latin_1')
arquivo = open('meu_arquivo.txt', 'r', encoding='latin1')  # alias de 'latin_1'
arquivo = open('meu_arquivo.txt', 'r', encoding='iso-8859-1')  # alias de 'latin_1'

arquivo = open('meu_arquivo.txt', 'r', encoding='ascii')
arquivo = open('meu_arquivo.txt', 'r', encoding='us-ascii')  # alias de 'ascii'
arquivo = open('meu_arquivo.txt', 'r', encoding='646')  # alias de 'ascii'
