Question

我做了一些谷歌搜索，遇到了下面的脚本，将DAT文件转换为CSV文件。

import csv
import idlsave
from os import listdir
from os.path import isfile, join, splitext

dat_folder = "C:\\Users\\ryans\\OneDrive\\Desktop\\dat\\"
csv_folder = "C:\\Users\\ryans\\OneDrive\\Desktop\\csv\\"

onlyfilenames = [f for f in listdir(dat_folder) if isfile(join(dat_folder,f))]
for fullfilename in onlyfilenames:
    file_name, file_extension = splitext(fullfilename)
    if file_extension == ".DAT":
        input_file = idlsave.read(dat_folder + fullfilename)
        n = input_file["raw"]
        with open(join(csv_folder, file_name + ".CSV"), "w", newline='') as f:
            writer = csv.writer(f)
            writer.writerows(n)

该代码看起来可以正常工作，并且逻辑看起来不错，但是当我运行它时，我收到以下错误消息：

Exception: Invalid SIGNATURE: b'10'

所有文件名和扩展名均大写。不知道这有什么区别。我搜索了错误，但没有提出任何有用的建议。

感谢Anil_M，这很有帮助！这是我的最终解决方案。

import csv
import idlsave
from os import listdir
from os.path import isfile, join, splitext

dat_folder = "C:\\Users\\ryans\\OneDrive\\Desktop\\dat\\"
csv_folder = "C:\\Users\\ryans\\OneDrive\\Desktop\\csv\\"

onlyfilenames = [f for f in listdir(dat_folder) if isfile(join(dat_folder,f))]
for fullfilename in onlyfilenames:
    file_name, file_extension = splitext(fullfilename)
    if file_extension == ".DAT":
        with open(join(dat_folder + fullfilename)) as f:
            with open(join(csv_folder, file_name + ".CSV"), "w") as f1:
                for line in f:
                    f1.write(line)

将文件夹中的所有DAT文件转换为CSV文件
