我在字典中有一本字典,如下所示:
{'ID1':{'sam':1,'maj':5, 'tif':7, 'paul':1},
'ID2':{'maj':4,'bib':5},
...}
如何将其写入 CSV 文件?我想为主键设置单独的积云,为内部键设置单独的列

希望这能为您指明正确的方向。假设您想按 ID 的排序顺序排列。
>> import csv
>>> d = {'ID1':{'sam':1,'maj':5, 'tif':7, 'paul':1},'ID2':{'maj':4,'bib':5},}
>>> with open('test.csv', 'w') as f:
fieldnames = ('sam', 'maj', 'tif', 'paul', 'bib')
w = csv.DictWriter(f, fieldnames)
for k, row in sorted(d.items()):
w.writerow(row)
>>> with open('test.csv') as f: # showing contents
print f.read()
1,5,7,1,
,4,,,5
我想这就是你要找的东西:
import csv
with open('/home/test/kelvin1/add.csv', 'wb') as csvfile:
kev = csv.writer(csvfile, delimiter=' ',
quotechar='|', quoting=csv.QUOTE_MINIMAL)
k ={'ID1':{'sam':1,'maj':5,'tif':7,'paul':1},'ID2':{'maj':4,'bib':5}}
for i in k:
kev.writerow(i)
for j in k[i]:
kev.writerow(j)
kev.writerow('%d' % (k[i][j]))
这段代码对我有用
