如何在生成的文本中一次读取一行请求？

Question

在Python 3中，我使用＆＃34;固定宽度文件＆＃34;来阅读链接。实施例

import requests
pagina = requests.get('http://idg.receita.fazenda.gov.br/orientacao/tributaria/cadastros/cadastro-nacional-de-pessoas-juridicas-cnpj/consultas/download/F.K03200UF.D71214AC')
only_text = pagina.text

only_text
'0107398403000180BOI GORDO AGROPECUARIA COMERCIO E REPRESENTACOES LTDA - EPP                                                                                                                   \n02073984030001802              49SELMA ELIANA MEDEIROS RIBEIRO                                                                                                                                \n02073984030001802              22MARCELO LUIZ SANCHES                                                                                                                                         \n0103173169000131CONSELHO ESCOLAR BOM JESUS

我需要阅读＆＃34; only_text＆＃34;的每一行。分别在每一行的某些位置提取字符串

我试过这个，但命令一次只占一个字符而不是每一行

for linha in only_text:
    print(linha)

请问，如何分别隔离和读取每一行？
