import platform as p

p1 = p.system()
path = 'C:WindowsSystem32driversetc'
os.chdir(path)
file = 'hosts'

def read_hosts():
    with open(file, 'r') as fs:
        data = fs.readlines()
    return data


if __name__ == '__main__':
    if p1 == "Windows":
        datas = read_hosts()
        for data in datas:
            print(data)

　　

因为直接读hosts文件没有权限所以使用了以下方法。

path = 'C:WindowsSystem32driversetc'
os.chdir(path)
file = 'hosts'
