Python：如何將元組值的字典寫入csv文件？

Question

如何將以下字典打印到csv文件中？

maxDict = {'test1': ('alpha', 2), 'test2': ('gamma', 2)} 

所以，該輸出CSV如下所示：

test1, alpha, 2 
test2, gamma, 2 

Answer 1

import csv 
with open("data.csv", "wb") as f: 
    csv.writer(f).writerows((k,) + v for k, v in maxDict.iteritems()) 

Answer 2

maxDict = {'test1': ('alpha', 2), 'test2': ('gamma', 2)} 
csvData = [] 
for col1, (col2, col3) in maxDict.iteritems(): 
    csvData.append("%s, %s, %s" % (col1, col2, col3)) 
f = open('test.csv', 'w') 
f.write("\n".join(csvData)) 
f.close()
