def save2csv(file_name=None, header=None, data=None):

:param file_name: 保存的文件名

:param header: 表头,每一列的名字

:param data: 具体填充数据

:return:

if file_name is None or isinstance(file_name, basestring) is False:

raise Exception('保存CSV文件名不能为空,并且必须为字符串类型')

if file_name.endswith('.csv') is False:

file_name += '.csv'

file_obj = open(file_name, 'wb')

file_obj.write(codecs.BOM_UTF8) # 防止乱码

if data is None or isinstance(data, (tuple, list)) is False:

raise Exception('保存CSV文件失败,数据为空或者不是数据类型')

if header is not None and isinstance(header, (tuple, list)) is True:

writer.writerow(header)

for row in data:

writer.writerow(row)

file_obj = open(file_name, 'wb')
