在CSV文件中編寫Python字典

Question

我想在CSV文件中編寫Python字典。 我的代碼是：

import csv
cluster = {}

cluster['cluster0'] = [0,'value1','value2','value3']

cluster['cluster1'] = [1,'value1','value2','value3']

csvfile2 = "//home/tom/Desktop/cluster.csv"

with open(csvfile2, "w") as output:
    writer = csv.writer(output, lineterminator='\n')
    writer.writerows(cluster)

但是沒有得到：

0,value1,value2,value3
1,value1,value2,value3

我的CSV文件中包含以下內容：

c,l,u,s,t,e,r,0
c,l,u,s,t,e,r,1

有什么建議嗎？

您應該調用.values()方法，而不要使用字典名稱。

with open(csvfile2, "w") as output:
    writer = csv.writer(output, lineterminator='\n')
    writer.writerows(cluster.values())

舉個例子：

d = {1: [1,2,3], 2: [4,5,6]}

>>> d.keys()
[1, 2]

>>> d.values()
[[1, 2, 3], [4, 5, 6]]
