只读特定行

Question

我只想读取某些行，例如从 0 到 10 的行，程序应该检查用户输入的数据的正确性。from ftplib import FTPfrom ftplib import error_permstart = 0 # some starting indexend = 5with open('string.txt', 'rb') as password_list:     for i,line in enumerate(password_list):       if(i>start & i<end):        line=line.replace(b'\n',b'').replace(b'\r',b'')        password=line.decode("utf-8")

Answer 1

尝试这个 ：

start = 0

end = 5

with open('string.txt', 'rb') as fh:

   lines = [i.replace(b'\n',b'').replace(b'\r',b'') for i in fh.readlines()][start:end]

   passwords = [i.decode('utf-8') for i in lines]
