Python根据列索引列表从枚举列表中选择特定的列值

Question

在下面的代码中：我正在读取文件，获取标题行，查找特定的标题列并存储它们的索引。然后我遍历其余的行，只想要那些索引的值。

    import csv       
def csvReader(csvFileName):
    counter = 10
    keyMap = []
    header = ["Test1","Test2"]
    with open(csvFileName,'r') as f:
        reader = csv.reader(f,skipinitialspace=True)
        Firstline = True
        print(reader)
        for row in reader:
            if counter > 0 and Firstline == True:
                print(list(enumerate(row)))
                indexes =[i for i, j in enumerate(row) if j in header]
                print(indexes)
                Firstline=False
                counter = counter - 1
            elif counter > 0:
                a = dict(zip(header, map((lambda str: row[i] for i in indexes) ,row)))
                print(a)
                print('test')
                counter = counter - 1
        return keyMap   
if __name__ == '__main__':
    csvReader("C:/Test.csv")

伙计 - 感谢您的回复。我刚修好了。改为以下：

a = dict(zip(header, map(str, (row[i] for i in indexes))))

但是，任何更好的解决方案，请分享。
