🔒 For Loop Not running

[stray birch]

Hello, I am trying to code a bot that will read data and then delete it. I have attached my code. The first for loop is not running at all (I've put a lot of print statements in it). Can someone please tell me where I'm going wrong?

async def on_ready():
    print('Bot is now online and ready to roll')
    lines=[]
    outfile = open("file.txt", "w+")
    lines = outfile.readlines()
    final = ""
    print("I work")
    for line in outfile:
        print("I also work")
        date_str = line.strip()
        print(date_str)
        date_str = line[:18]
        print(date_str)
        date_format = '%Y-%m-%d %H:%M:%S'
        date_obj = datetime.datetime.strptime(date_str, date_format)
        print(date_obj)
        now = datetime.datetime.now()
        print(now)
        diff = date_obj-now
        print(diff)
        seconds = diff.total_seconds()
        print(seconds)
        if seconds > 0:
            print("running")
            await asyncio.sleep(seconds)
            await bot.wait_until_ready()
            remind_channel = bot.get_channel(channel)
            await remind_channel.send("<@role> time to post ad!")
            print("ran")
    for number, vert in enumerate(lines):
        if number != 0:
            final = final + vert
    outfile.write(final)
    outfile.close()

    ========= ===============================================================
    Character Meaning
    --------- ---------------------------------------------------------------
    'r'       open for reading (default)
    'w'       open for writing, truncating the file first
    'x'       create a new file and open it for writing
    'a'       open for writing, appending to the end of the file if it exists
    'b'       binary mode
    't'       text mode (default)
    '+'       open a disk file for updating (reading and writing)

yes, I need it to be able to read and write

are you saying it should just be + and not w+?

[ashen hound]

truncating the file first
w empties the file, hence the for loop has nothing to loop on

[stray birch]

I tried doing r+, but then it said the content was unwritable

I just tried again, and the for loop still didn't work

[ashen hound]

    lines = outfile.readlines()
    final = ""
    print("I work")
    for line in outfile:

You have read the file, and moved the pointer to the end of the file.
Then you ask it to read from the pointer, which is at the end of the file.

Perhaps you should be looping through lines 🤷‍♂️ I haven't read through all of the code you gave.

[stray birch]

Oh, I see. should I do a seek then?
