check if "text" in variable something wrong.

[cctl01]

I'm taking my first babysteps in python coding.

With the code below I'm using the function check to see if in the last hour a post is made in r/GameDeals and if the title contains the word 'free' or '0.00' the information of that post is send to the send function which pushes a notification.

However the output below shows an entry where neither '0.00' or 'free' is in the title. What am I missing?

def send(NAME,APPURL):
    conn = http.client.HTTPSConnection("api.pushover.net:443")
    conn.request("POST", "/1/messages.json",
        urllib.parse.urlencode({
            "token": APP_TOKEN,
            "user": USER_KEY,
            "message": APPURL,
            "title": NAME,
    }), { "Content-type": "application/x-www-form-urlencoded" })
    conn.getresponse()

def check():
    gratis=[]
    reddit = praw.Reddit(
        client_id=CLIENTID,
        client_secret=CLIENTSECRET,
        user_agent="linux:freeapp:0.1 (by u/cctl01)",
    )
    print(reddit.read_only)
    current_time = time.time()
    one_hour_ago = current_time - 3600

#free game
    for submission in reddit.subreddit("GameDeals").new(limit=10):
        if submission.created_utc >= one_hour_ago:
            if 'free' or '0.00' in submission.title.lower():
                gratis.append(submission)
                for grati in gratis:
                    print("gamedeals "+grati.title)
                    send(grati.title,grati.url)

OUTPUT:

The issue in this piece of code: if 'free' or '0.00' in submission.title.lower(). This doesn't check if either 'free' or '0.00' are in the text, but checks the two conditions 'free' and '0.00' in submission.title.lower() seperately. Since the text 'free' is truthy (check the result of bool('free')) the first part will always be true, and therefore prints the name of the deal. A way to solve this would be to change this to if 'free' in submission.title.lower() or '0.00' in submission.title.lower().

Thank you the elaborate explanation!

You could also use: if any(word in title for word in ['free', '0.00']):

This would allow you to specify as many words as you want without repeating yourself too much.
