在CSV文件中编写Python字典

Question

I would like to write a Python dictionary inside a CSV file. My code is:

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)

But instead of getting:

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

I have inside my CSV file:

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

Any suggestion please?

Instead of the dictionary name, you should call the .values() method

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

As an example:

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

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

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