Sending qr codes to discord user

Question

My discord bot creates qr-codes after a certain command. However I am unable to send this qr-code to the user as message:

import qrcode

def create_qr_code(string : str):

    qr = qrcode.make(string)
    return qr


# sending qr to user
qr_code = create_qr_code('some text')
# check if qr_code is None
print(qr_code)
await ctx.send(file=discord.File(fp=qr_code))

My print statement returns something like

<qrcode.image.pil.PilImage object at 0x000001BD735FCF28>,

which is fine and shows me that the creation of the qr code was successful. I wonder why sending it doesn't seem to work.

Answer 1

Actually I found a working solution myself using this solution:

First of all I create a qr code and return this object

import qrcode

def create_qr_code(string : str):

    qr_code = qrcode.make(string)
    return qr_code

I can now use BytesIO() to send this qr code as binary file to discord:

import io

def some_other_function():

    qr_code = create_qr_code('my string')

    with io.BytesIO() as image_binary:
        qr_code.save(image_binary, 'PNG')
        image_binary.seek(0)
        await ctx.send(file=discord.File(fp=image_binary, filename='qr.png'))
