Create a dictionary with multiple value-CodePudding

I have a file containing mac_address, RSSI value and time value; I want create a dictionary where the keys are the mac_address and the values are the RSSI and time. How can I do this?

The file is formatted as this:

6E:C6:F8:89:AE:64  -71dBm   10:18:25
C4:A5:DF:24:05:7E  -45dBm   10:18:26
B0:6E:BF:1F:5E:A1  -27dBm   10:18:48

But I can have more than 3 row sometimes

You can use a dictionary comprehension:

with open('file.txt') as f:
    mac_dic = {k:tuple(v) for k,*v in map(str.split, f.readlines())}

output:

>>> mac_dic
{'6E:C6:F8:89:AE:64': ('-71dBm', '10:18:25'),
 'C4:A5:DF:24:05:7E': ('-45dBm', '10:18:26'),
 'B0:6E:BF:1F:5E:A1': ('-27dBm', '10:18:48')}

Here is an alternative format:

with open('file.txt') as f:
    mac_dic = {k:dict(zip(['RSSI', 'time'], v))
               for k,*v in map(str.split, f.readlines())}

>>> mac_dic
{'6E:C6:F8:89:AE:64': {'RSSI': '-71dBm', 'time': '10:18:25'},
 'C4:A5:DF:24:05:7E': {'RSSI': '-45dBm', 'time': '10:18:26'},
 'B0:6E:BF:1F:5E:A1': {'RSSI': '-27dBm', 'time': '10:18:48'}}

Using type hints and NamedTuple

from typing import NamedTuple,Dict

class RSSI(NamedTuple):
  rssi: str
  time:str

mac = str

data: Dict[mac,RSSI] = dict()  
with open('test.txt') as f:
  for line in f:
    mac,rssi,time = line.split()
    data[mac] = RSSI(rssi,time)
print(data)

output

{'6E:C6:F8:89:AE:64': RSSI(rssi='-71dBm', time='10:18:25'), 'C4:A5:DF:24:05:7E': RSSI(rssi='-45dBm', time='10:18:26'), 'B0:6E:BF:1F:5E:A1': RSSI(rssi='-27dBm', time='10:18:48')}
