写入 CSV 文件，选择要写入的列

Question

我正在尝试从包含一些关于文本的数据的 X（在本例中为 6 个）CSV 文件导入数据，并将每个文档中的一个特定行放到一个新行上，这样它们就会出现在每个文档旁边其他（从第 1 列的文档 1 导出，从第 2 行的第二个文档导出，依此类推）。到目前为止，我一直没有成功。

    # I have a list containing the path to all relevant files
    files = ["path1", "path2", ...]

    # then I tried cycling through the folder like this
    for file in files:
        with open(file, "r") as csvfile:
            reader = csv.reader(csvfile, delimiter=",")
            for row on reader:
                # I'm interested in the stuff stored on Column 2
                print([row[2]])
    # as you can see, I can get the info from the files, but from here 
    # on, I can't find a way to then write that information on the 
    # appropiate coloumn of the newly created CSV file

编辑：我知道如何打开编写器，但我不知道如何编写一个脚本，每次处理一个新文件时，该脚本将从原始 6 个文档中获取的信息写入不同的列。

# I have a list containing the path to all relevant files
files = ["path1", "path2", ...]
newfile = "newpath1"

# then I tried cycling through the folder like this
for file in files:
    with open(file, "r") as csvfile:
        reader = csv.reader(csvfile, delimiter=",")
        with open(newfile, "a") as wcsvfile:
            writer = csv.writer(wcsvfile)
            for row on reader:
                # I'm interested in the stuff stored on Column 2
                writer.writerow([row[2]])
