Reference new dictionary keys with a variable

[slouw]

I want to read text files with parameters and assignments in order to configure a new device.
It seemed correct to read variables and their assignments into a dictionary from a text file.
But I have hit a snag in that I cannot work out how to read variables directly into a dictionary.
I have stripped down my script to the following to try and illustrate this.

Grateful for any replies..

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43

# $language = "python" # $interface = "1.0" # import time import datetime import sys   #!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! # This is how I want me dictionary to look after # assignment from reading a text file #!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!   Dict_Param = { "<IP_ADDRESS>": "10.10.10.10", "<PREFIXLENGTH>": "24", "<HOSTNAME>": "blahblah" }     Dict_Param = {}   #!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! # Variables and their assignments are read from # a text file into 2 lists as shown # I have this working just stripped out for simplicity #!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! KeyStr = ["<IP_ADDRESS>","<PREFIXLENGTH>","<HOSTNAME>"] AssignStr = ["10.10.10.10", "24", "blahblah"]   #!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! # This does not work # But I hope it illustrates what I am trying # and failing to do # That is add the pairs defined in the 2 lists above # as key entries in my dictionary #!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!   Dict_Param['KeyStr[0]'] = AssignStr[0] Dict_Param['KeyStr[1]'] = AssignStr[1] Dict_Param['KeyStr[2]'] = AssignStr[2]   print Dict_Param #!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Dict_Param['KeyStr[0]'] = AssignStr[0] Dict_Param['KeyStr[1]'] = AssignStr[1] Dict_Param['KeyStr[2]'] = AssignStr[2]

Remove the quotes, and that would work as you expect.

Or, you can do it the easy way and use a loop:

1 2 3 4 5

for index in range(len(KeyStr)):     if index < len(AssignStr):         key = KeyStr[index]         val = AssignStr[index]         Dict_Param[key] = val

keys = ["<IP_ADDRESS>","<PREFIXLENGTH>","<HOSTNAME>"] values = ["10.10.10.10", "24", "blahblah"] dict_params = dict(zip(keys, values))

but it's interesting how you end up with two lists by reading from a text file - you can read from file line by line and directly assign value to key in the dict. I don't give example, because it's not clear how the file looks like

You can use zip to pair up the key and value in a for loop

1 2 3 4 5 6 7 8 9

dict_param = {}   keystr = ["<IP_ADDRESS>","<PREFIXLENGTH>","<HOSTNAME>"] assignstr = ["10.10.10.10", "24", "blahblah"]   for key, value in zip(keystr, assignstr):     dict_param[key] = value       print(dict_param)

Output:
{'<IP_ADDRESS>': '10.10.10.10', '<PREFIXLENGTH>': '24', '<HOSTNAME>': 'blahblah'}
