Python CSV写入器：写入不均列

Question

我想写入具有不均匀列的行。下面是我的代码：

import csv 
import json 

path = 'E:/Thesis/thesis_get_data' 
outputfile = open('maplight_113.csv', 'w', newline='') 
outputwriter = csv.writer(outputfile) 

with open (path + "/" + 'maplight data 113congress.json',"r") as f: 
    data = json.load(f) 

    for bill in data['bills']: 
     b = bill.get('measure') 
     for organization in bill['organizations']: 
      d = organization.get('name') 
      f = organization.get('disposition') 
      a = (organization.get('catcode')) 

      outputwriter.writerow([b, d, a, f]) 
      outputfile.flush(); 

每个“bill.get（‘测量’）”在我的数据，可能有“d，F，A”，从“账单[组织']”的一组或多组与之相关联。我希望每一组“d，f，a”在同一个“bill.get（'measure'）”行中填写其他列。

这是怎么回事？

with open (path + "/" + 'maplight data 113congress.json',"r") as f: 
    data = json.load(f) 

    for bill in data['bills']: 
     b = bill.get('measure') 
     tmp = [(x.get('name'), x.get('catcode'), x.get('disposition')) for x in bill['organizations']] 
     outputwriter.writerow(chain((b), *tmp)) 
     outputfile.flush() 

您需要：

from itertools import chain
