python读取csv文件

python读取csv文件一般用于批量导入数据

    def uploadfile(cls, file):
        results = {'usr_err_mes': 0, 'data': [], 'info': []}
        csv_data = []
        # 此处的参数分别是从前台传递的csv文件,只读模式，gbk支持中文
        with open(file, "r", encoding='gbk') as csvfile:
        	# 此处是为了避免空白项的报错，因为csv不识别\0
            reader = csv.DictReader((line.replace('\0', '') for line in csvfile))
            for line in reader:
                if not line:
                    break
                else:
                    csv_data.append(line)
        if not csv_data:
            raise ValueError(_('There is no data in csv file'))
        else:
        	pass
 #csv_data = [{"ip": "1.1.1.1", "community": "cisco"}, {}]
