对文本文件中的字典列表进行排序

Question

I currently have a list of arrays which include a list of dictionaries in a text file. I have attempted to import json to use that inbuilt function however it didn't work with the format of the text file. Any suggestions on how to make it work. My other strategy involved manually filtering the values however I hit a snag since "bankroll" is mentioned in both public and private.

    bankroll=[]
with open("abc.txt", "r") as b:
    lines=b.readlines()
for line in lines:
    if "bankroll" in line:
        key, value = [x.strip() for x in line.strip().split(':', 1)]
        bankroll.append[value]

[
{
    "private": {
        "bankroll": 1000,
        "last_bid": 0,
        "launching": false,
        "name": "abc",
        "tech": 0
    },
    "public": {
        "auction_round": 0,
        "game_stage": "start",
        "last_mining_payoff": 0,
        "last_winning_bid": 0,
        "last_winning_bidders": [],
        "last_winning_miner": "",
        "max_rounds": 201,
        "players": {
            "AggressiveLauncher": {
                "bankroll": 1000
            },
            "abc": {
                "bankroll": 1000
            },
            "PassiveLauncher": {
                "bankroll": 1000
            },
            "def": {
                "bankroll": 1000
            },
            "SpongeBob": {
                "bankroll": 1000
            }
        },
        "round": 0
    }
},

Above is an example of a singular element of many, in one of many arrays in the text file.

Using json should be straightforward:

>>> lines = '''
[
   {
    "private": {
        "bankroll": 1000,
        "last_bid": 0,
        "launching": false,
        "name": "abc",
        "tech": 0
    },
    "public": {
        "auction_round": 0,
        "game_stage": "start",
        "last_mining_payoff": 0,
        "last_winning_bid": 0,
        "last_winning_bidders": [],
        "last_winning_miner": "",
        "max_rounds": 201,
        "players": {
            "AggressiveLauncher": {
                "bankroll": 1000
            },
            "abc": {
                "bankroll": 1000
            },
            "PassiveLauncher": {
                "bankroll": 1000
            },
            "def": {
                "bankroll": 1000
            },
            "SpongeBob": {
                "bankroll": 1000
            }
        },
        "round": 0
    }
},
{
    "private": {
        "bankroll": 1000,
        "last_bid": 0,
        "launching": false,
        "name": "abc",
        "tech": 0
    },
    "public": {
        "auction_round": 0,
        "game_stage": "start",
        "last_mining_payoff": 0,
        "last_winning_bid": 0,
        "last_winning_bidders": [],
        "last_winning_miner": "",
        "max_rounds": 201,
        "players": {
            "AggressiveLauncher": {
                "bankroll": 1000
            },
            "abc": {
                "bankroll": 1000
            },
            "PassiveLauncher": {
                "bankroll": 1000
            },
            "def": {
                "bankroll": 1000
            },
            "SpongeBob": {
                "bankroll": 1000
            }
        },
        "round": 0
    }
}]

In your case, you can directly de-serialize from your file object, using json.load :

>>> with open("abc.txt", "r") as b:
        lines = json.load(b)
