如何使用 Python 动态创建列表字典

问题描述

我要处理这个输入：

['','','  Huawei Integrated Access Software (MA5600T).','  copyright(C) Huawei Technologies Co.,Ltd. 2002-2014. All rights reserved.','  -----------------------------------------------------------------------------','  User last login @R_977_4045@ion:','  Access Type : Telnet ','  IP-Address  : 1.1.1.1','  Login  Time : 2020-12-24 11:51:33+01:00','  logout Time : 2020-12-24 11:51:38+01:00','OLT-SALUZZO_01>enable','OLT-SALUZZO_01#display ont autofind all \x1b[1D\x1b[1C','   ----------------------------------------------------------------------------','   Number              : 1','   F/S/P               : 0/17/7','   Ont SN              : 485754437D85CA9E (HWTC-7D85CA9E)','   Password            : 0x00000000000000000000','   Loid                : ','   Checkcode           : ','   vendorID            : HWTC','   Ont Version         : 159D.A','   Ont Softwareversion : V5R019C00S100','   Ont EquipmentID     : EG8145V5','   Ont autofind time   : 2020-12-24 08:38:28+01:00','   Number              : 2','   Ont SN              : 48575443A9517A9E (HWTC-A9517A9E)',"---- More ( Press 'Q' to break ) ----"]

我需要从中创建这样的输出：

[{'F/S/P': '0/17/7','SN': ' 485754437D85CA9E','Password': None},{'F/S/P': '0/17/7','SN': '48575443A9517A9E ','Password': None}]

我的功能是这样的：

tn.write("display ont autofind all ".encode('utf-8') + b"\n")
return_lineid = tn.read_until('The number of GPON'.encode('utf-8'),3).decode('utf-8')
data_return = return_lineid.splitlines()
autofind_list=[]
records = []
current_record = {}
for line in data_return:
    line = line.strip()
    if not line:  # empty line
        records.append(current_record)
        current_record = {}
    else:
        if "F/S/P" in line:
            key,value = line.split(':')
            key = key.strip()
            value = value.strip()
            current_record[key] = value
            print(current_record)
        if "Ont SN" in line:
            key,value = line.split(':')
            key = key.strip()
            value = value.strip()
            value = re.sub(r'\(.*\)',value)
            current_record[key] = value
            print(current_record)
        if "Password" in line:
            key,value = line.split(':')
            key = key.strip()
            value = value.strip()
            if value == '0x00000000000000000000':
                current_record[key]=None
            else:
                current_record[key] = value

        autofind_list.append(current_record.copy())

#for removing same records
seen = set()
new_l = []
for d in autofind_list:
    t = tuple(d.items())
    if t not in seen:
        seen.add(t)
        new_l.append(d)

print(new_l)

但它返回这个，我几乎达到了我的目标：

[{},{'F/S/P': '0/17/7'},'Ont SN': '485754437D85CA9E '},'Ont SN': '485754437D85CA9E ','Ont SN': '48575443A9517A9E ','Password': None}]

但我想删除无用的对象，如 {},{'F/S/P': '0/17/7'}

有人可以帮我解决这个问题吗？或者可以给我一个提示？
