Defining a Function

[mattt1998]

I have this code that sorts a document according to the words it contains. There is a pythonic way of counting the files classified as "_fruit" and "_veget" that I am moving to the folder untitled1

path_txt = 'temp'
files1 = os.listdir(path_txt)
for TXT in files1:
    with open(path_txt + '\\' + TXT, "r") as content: 
        key1 = False
        key2 = False
        search = re.search(r'\d{21,30}', content.read())        
        text = content.read()
        if ('apple' in text and 'banana' in text and 'orange') or \
                ('apple' in text and 'orange' in text and 'watermelon'):
            key1 = True
        elif ('pumpkin' in text or 'potato' in text) and \
                        'carrot' in text and '' in text and \
                        'beet' in text and not 'pineapple' in text and not 'orange' in text:
            key2 = True
    if search is not None:  
        name1 = search.group(0)         
        if key1:
            fp = os.path.join("untitled1", name1 + '_fruit' + "_%d.txt")
            postfix = 0
            while os.path.exists(fp % postfix):
                postfix += 1
        elif key2:
            fp = os.path.join("untitled1", name1 + '_veget' + "_%d.txt")
            postfix = 0
            while os.path.exists(fp % postfix):
                postfix += 1
        os.rename(
            os.path.join(path_txt, TXT),
            fp % postfix
        )

ps: I have 8 "for" loops in the same code doing similar things. I will apply for them as well.
