我正在做一些导出到csv，我的字段名有问题。 我想要3行“fieldnames”
Row 1 : Field 1:empty ; Field 2:"YEAR" , Field3:"2017"
Row 2 : Field 1:empty ; Field 2:"MONTH", Field3: month.number
Row 3 : Field 1:"STATION"; Field 2:"CODE" , Field3: day.number
由于我不知道如何联合细胞，因此2017年将所有细胞合并到12/365细胞之上，或者每个月（例如Jan）将31个细胞合并在一起。我用2017年或1月打印每个单元格（31次） 2月（28次）等。

但是，我在csv中得到的标题是：
Row 1: empty, Year, 2017, 2017 ... (correct)
Row 2: Empty, Month, May, May ... (should be Jan not May)
Row 3-360+: Station, Code, 15, 15 ... (should be 01, 02, ..,31, 01, 02... and so on)
有什么建议吗？ 提前谢谢！
PS：输出就像
empty, YEAR, 2017, 2017, 2017....*365
empty, MONTH, Jan, Jan, Jan...*31, Feb, Feb...*28.....
STATION, CODE, 01, 02, 03..., 31, 01, 02,...,28, 01.....
答案 0 :(得分：1)
修改csv writer方法和main以获取列表并将其写入您的文件！
#to CSV
def csv_writer(path, data):
with open(path, "wb") as out_file:
for row in data:
out_file.write(','.join(row))
out_file.write('\n')
###Creating CSV
if __name__ == "__main__":
data=[heady.split(","),
headm.split(","),
headd.split(",")]
#data = zip(*data)
print data
path = "dict_output.csv"
csv_writer(path, data)
示例输出：
