使用 Python 从 .txt 文件中创建 JSON

Question

This is what the data looks like in the txt file (tab delimited):

President, U.S. Vote For 1  0 of 1,599 precincts reporting
Candidate   Party   Votes
Deval Patrick   DEM 0
Bernie Sanders  DEM 0
Joseph R. Biden DEM 0
Michael R. Bloomberg    DEM 0
Elizabeth Warren    DEM 0
Pete Buttigieg  DEM 0
Tom Steyer  DEM 0
Andrew Yang DEM 0
Michael Bennet  DEM 0
John K. Delaney DEM 0
Tulsi Gabbard   DEM 0
Cory Booker DEM 0

This is the schema for the JSON I want to create:

"races": [ {   
        "name": "President, U.S.",
        "reference_id": "US-President",
        "election_date": "2020-03-17",
        "market": "balt",
        "state_postal": "MD",
        "reporting_units": [
            {
                "name": "US",
                "level": "fed",
                "state_postal": "MD",
                "precincts_reporting": 0,
                "total_precincts": 1599,
                "data_source_update_time": "2020-02-25T19:54:23+0000",
                "candidates": [
                    {
                        "last_name": "Patrick",
                        "middle_name":null,
                        "first_name":"Deval",  
                        "party": "DEM",
                        "vote_count": 0,
                    }, ...
                ]
            }
        ]
    }
 ]

So the candidates object would have to exist for each candidate, and there are many more races that are included in the txt file. I know I'd use json.dumps for this but I'm really struggling with the syntax of how to address each row of this text file.

If your source file is regular, you may want to consider parsing the file line-by-line to read it into python:

with open(path_to_file, 'r') as f:
    # Loop through each line;
    # Separate logic for parsing 1st line and subsequent lines, 
    # along with any other cases you have to consider
