删除列表括号时python从字典写入csv

我有一个字典列表，其中的值是列表。我想将其写入csv文件，同时删除[]。但是当我运行下面的代码时，它会写出csv，但会保留[]。没有这个我怎么写

data_list_of_dx = [{'a_id':['NC01'],'org_id':['FX0'],'status':['Active','Current']}, {'a_id':['bC01'],'org_id':['dr0'],'status':['Dormant','Current']},{'a_id':['NC02'],'org_id':['TX0'],'status':['Active','Late']}, {'a_id':['ty01'],'org_id':['t00r0'],'status':['New','Current']}]
fieldnames = ['a_id','org_id','status']
g_n = 'test_ct_data_2.csv'
g = open( g_n , 'w', encoding = 'utf-8' , newline ='')
writer = csv.DictWriter( g , fieldnames = fieldnames )
writer.writeheader()
for row in data_list_of_dx:
 writer.writerow(row)
g.close()

在将dict写入csv之前，可以对dict中的值使用

str.join

Ex:

data_list_of_dx = [{'a_id':['NC01'],'org_id':['FX0'],'status':['Active','Current']}, {'a_id':['bC01'],'org_id':['dr0'],'status':['Dormant','Current']},{'a_id':['NC02'],'org_id':['TX0'],'status':['Active','Late']}, {'a_id':['ty01'],'org_id':['t00r0'],'status':['New','Current']}]
fieldnames = ['a_id','org_id','status']
g_n = 'test_ct_data_2.csv'
g = open( g_n , 'w', encoding = 'utf-8' , newline ='')
writer = csv.DictWriter( g , fieldnames = fieldnames )
writer.writeheader()
for row in data_list_of_dx:
    val = dict((k, ",".join(v)) for k, v in row.items())
    writer.writerow(val)
g.close()

• 最好将

  与open（）一起使用（

  Ex:

  与open（g_n，'w'，encoding='utf-8'，newline=''）作为g:

什么是字段名？更新代码以添加字段名。谢谢，这很有效。我想我会加入使用“；”而不是“，”。这将防止它在我读取csv文件时崩溃。我投了赞成票，但我如何接受它？另外，为什么“with open（）”更好？用
