Question

我正在尝试将Python脚本here用于我自己的目的。我不是Python的家伙，所以希望有人能看出我的错误。这是缩进错误吗？

Traceback (most recent call last): File "test.py", line 31, in <module> csv_doc.write( ouput_to_csv.join("\n") ); NameError: name 'ouput_to_csv' is not defined

其次，此脚本创建CSV。我想跳过这一步，使用MySQLdb将数据直接写入数据库中的表。这可能吗？

# import the standard libraries you'll need
import os # https://docs.python.org/2/library/os.html
import re # https://docs.python.org/2/library/re.html

# this function will walk your directories and output a list of file paths
def getFilePaths(directory):
    file_paths = []
    for root, directories, files in os.walk(directory):
        for filename in files:
            filepath = os.path.join(root, filename)
            file_paths.append(filepath)
    return file_paths

audio_file_paths = getFilePaths("Z:\Dropbox\Apps\DirScan\files")
output_to_csv = [];

for audio_file in audio_file_paths:
    base_path, fname = os.path.split(audio_file) 

    reg_ex = re.compile("^(.*) - (.*) - (.*).mp3$");

    # now apply the compiled regex to each path
    name_components = reg_ex.match(fname);

    output_to_csv.append("{0},{1}".format(name_components.join(","), base_path));

#create the file, making sure the location is writeable
csv_doc = open("database.csv", "w");

# now join all the rows with line breaks and write the compiled text to the file
csv_doc.write( ouput_to_csv.join("\n") ); 

#close  your new database
csv_doc.close()

背景是我想使用正则表达式将文件夹中的audiofiles导入数据库。格式为Artist - Title - Other info.mp3

你写ouput_to_csv必须output_to_csv你省略t

Script＆amp;上的NameError数据库插入
