我有一本看起来像这样的字典
{ 1: ['apple', 'orange'],
2: ['fennel', 'basil', 'bay leaves'],
3: ['almonds', 'walnuts']}
我尝试将其导出为CSV并让表格如下所示:
list_id list_items
1 apple
1 orange
2 fennel
2 basil
2 bay leaves
3 almonds
3 walnuts
我不知道如何做的主要事情是如何解析字典中的多个值,以便我有单独的行。我已查看了csv.writerow()
,但文档并不是非常有用,所以我非常感谢您的示例!

循环遍历字典键/值,然后遍历值:
import csv
D = { 1: ['apple', 'orange'],
2: ['fennel', 'basil', 'bay leaves'],
3: ['almonds', 'walnuts']}
# with open('out.csv','w',newline='') as f: # Python 3
with open('out.csv','wb') as f: # Python 2
w = csv.writer(f)
w.writerow(['list_id','list_items'])
for key,items in D.items():
for item in items:
w.writerow([key,item])
