如何将不同的文本输出到单独的文件中？ python3

Question

所以我试图制作一个机器人，它在比较两个文本文件（使用 requests.get('url=').text 方法生成）后发送一条消息，只显示新的 lines/text/whichever 已经 added/removed.

我知道有 difflib。 HtmlDiff(make_file()) 不适合我，因为它只会弄乱文件。另外，据我所知，它只需要输出一个 html 文件。然后你在浏览器和 Wuala 中打开它！你有比较。

我尝试搜索，但找不到这样的库，它只输出已经 changed/added.

的文本

目前我是这样做的：

def htmlCompare(prep_id=None):
while True:
    prep_url = requests.get(prep_template.format(prep_id))
    c1 = prep_url
    c2 = ''
    if c2 != c1:
        compare = difflib.HtmlDiff().make_file(fromlines=c1, tolines=c2, numlines=1)
        c2 = c1
        config_compare_save = open('compare_{}_main.txt'.format(prep_id), 'w')
        config_compare_save.write(compare)
        config_compare_save.close()
    else:  # don't mind this meaningless condition for now, I left this for something for later :)
        time.sleep(10)

但这并没有给我我需要的结果，如您所知。试过用Differ()，但好像不知道怎么用。甚至不确定这是否是我首先需要使用的方法。但据我所知，这是最接近我可能需要使用的。

Question: Tried to use Differ(), ... from what I can tell, this is the closest to what I might have to use.

注意：只有..._data的第行等于！

import difflib

_old_data = "refno,title,author,year,price\n\
1001,CPP,MILTON,2008,456\n\
1002,JAVA,Gilson,2002,456\n\
1003,Adobe Flex,,2010,566\n\
1004,General Knowledge,Sinson,2007,465\n\
1005,Actionscript,Gilto,2008,480\n".splitlines(keepends=False)

_new_data = "refno,title,author,year,price\n\
1001,CPP,MILTON,2010,456,2008\n\
1002,JAVA,Gilson,2002\n\
1003,Adobe Flexi,Johnson,2010,566\n\
1004,General Knowledge,Simpson,2007,465\n\
105,Action script,Gilto,2008,480\n\
2000,Drama,DayoNe,,2020,560\n".splitlines(keepends=False)

diff = difflib.Differ()

for line in diff.compare(_old_data, _new_data):
    if line.startswith(('?',' ')):
        # Skip diff control lines ?
        # Skip equal lines ' '
        pass
    else:
        #print(line[2:])
        print(line)
