Python：如何将元组值的字典写入 csv 文件？

Question

如何将以下词典打印到 csv 文件中？

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

因此，输出 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()
