ddt csv写入数据报错

#csv 文件读取
import csv




class CsvDate():
    def Date(self):
        csv_path = r"E:\QQ File\TestRace\testdata.csv"

        with open(csv_path, "r", encoding="utf-8") as f:
            csvreader = csv.reader(f)
            data_list = []
            i=0
            for getDate in csvreader:
                if i!=0:
                    data_list.append(getDate)
                i+=1
        return data_list





if __name__ == '__main__':
    DateClass = CsvDate()
    Date = DateClass.Date()
    print(Date)

打印结果 [['5555222', '九月十四日1'], ['5555223', '九月十四日2'], ['5555224', '九月十四日3'], ['5555225', '九月十四日4']]

报错信息  TypeError: test_Question_three() missing 2 required positional arguments: 'data' and 'data2'

问题点： 要在测试类Test_Question_three上加@ddt.ddt,否则会报错

代码修改如下:

#csv 文件读取
import csv
 

class CsvDate():
    def Date(self):
        csv_path = r"E:\QQ File\TestRace\testdata.csv"
 
        with open(csv_path, "r", encoding="utf-8") as f:
            csvreader = csv.reader(f)
            data_list = []
            i=0
            for getDate in csvreader:
                if i!=0:
                    data_list.append(getDate)
                i+=1
        return data_list

这个报错说明test_Question_three()方法缺少两个必需的位置参数：data和data2。根据代码中的@ddt.unpack装饰器，测试方法的参数应该与@ddt.data装饰器传递的csv数据的列数相匹配。

请确保@ddt.data装饰器传递的csv数据有两列，并在test_Question_three()方法中正确命名和使用这两个参数。例如：

@ddt.data(*CsvDate().Date())
@ddt.unpack
def test_Question_three(self, data1, data2):
    # test logic

请检查一下你的csv数据是否包含了正确的列数，并确保参数名称与csv数据列的内容一致。

如果问题仍然存在，请提供更多相关的代码和示例数据，以便我能够更好地帮助你解决问题。

读取csv文件打印出来的 [['5555222', '九月十四日1'], ['5555223', '九月十四日2'], ['5555224', '九月十四日3'], ['5555225', '九月十四日4']]
