如何使用pandas或csv在每10-15行具有相同标题后读取python中csv文件的每一列？

我有一个CSV文件，下面的文件中有类似的数据

我需要阅读CSV文件，我正在使用Pandas来构造和组合所有列，以及客户姓名和电话号码，以了解他们的品牌和型号。输出为以下文件

下面是我尝试过的代码，我无法进一步了解如何循环第2列并在解析第1列后获取详细信息

import pandas as pd

hdf = pd.read_csv("file.csv", nrows=0)
first = list(hdf)
df = pd.read_csv("file.csv", skiprows=1) 
df.columns = ['A','B','C','D']
out_df = pd.DataFrame(columns=['Column', 'Customer', 'fname', 'lname', 'phone', 'make', 'model'])
out_df.Customer = i.A
out_df.fname = i.B
out_df.lname = i.C
out_df.phone = i.D
out_df.Column = first[0]
out_df.make = first[2]
out_df.model = first[4]
out_df.to_csv('new_file.csv')

这就是我无法前进的地方。有没有其他类似的问题，我可以从中找到一些关于如何获得期望结果的想法

非常感谢您的帮助

谢谢大家!

我将使用csv.DictReader从文件中读取行，检查条件，即第一列为“Customer”或“column x”，并将值分配给列表。最后，将列表转换为所需的数据帧

输入csv文件test.csv：

代码：

结果:
