QUESTION
I want to make a QR code with python. The output is a white background with a black qr code. How do I change both of them?
...ANSWER
Answered 2022-Mar-09 at 14:57The documentation of this module can be found here: PyQRCode Module Documentation
It says that the various methods of this module (e.g. png, if you want to get the QR code as a png image) take a background parameter that lets you define the background color, as well as a module_color parameter for the code itself.
QUESTION
I am having trouble setting the inheritance. I want to activate the generator function when the pushButton_3 is clicked but I keep getting the error in the title. My full code:
ANSWER
Answered 2022-Mar-05 at 12:06self.pushButton_3.clicked.connect(self.generate()) at this line you are not connecting the generate function but you are calling it by adding () to function name, so change it to self.pushButton_3.clicked.connect(self.generate) and self.generate should accept one argument x which is callback event of pushbutton
so either change definition of self.generate which accepts one argument
or make a lambda function which accepts one argument and calls self.generate by placing this line self.pushButton_3.clicked.connect(lambda x: self.generate())

QUESTION
I was trying to create a QRcode generating app in python with tkinter that you enter color and then text and it generates a QRcode but it closes instantly upon startup. (the problem did not happen when I didn't have the color part), (in the future I'm also planning to add a save QR as png button) here's what I have:
...ANSWER
Answered 2021-Sep-19 at 14:01The reason the program closes immediately is because there is no root.mainloop(). Even if there was, there are a lot of other errors that would prevent the program from working.
The first problem is if 'x' == 1. Here you are comparing the literal string "x" to the number 1. These are never going to be equal, so the other window will never show up. I can see what you are trying to do with x, but it won't work as you expect. It is better just to get rid of x completely and call a function after the user selects a colour. I've called this function show_qr_window.
The second problem is how you get the hex code. You use the output of colorchooser.askcolor, which is a tuple containing an rgb tuple representing the colour and it's hex value. You only want the hex value, so you want color_code[1], as the hex value is the second item. I've also added an if statement to make sure color_code is not None. color_code will be None if the user does not choose a colour and just closes the window. If the user has chosen a colour, it is passed to show_qr_window. Because we've checked the user has chosen a colour, you can get rid of all of the other validation as colorchooser will always return a valid hex value. You also no longer have to import re.
The third issue is that you've used Tk twice. This will cause your program to not work properly. Instead, change ws = Tk() to ws = Toplevel().
The next issue is str = 'color_code'. This is not how you define a variable. You want to do color_code = 'a string'. In this case, the string is passed to show_qr_window as the variable color, so you can use color_code = color. You also have to change all of the bg = 'color_code' to bg = color_code, as color_code is a variable, not a string.
The rest of your code seems to work (I haven't tested the qr code generation as I don't have that module installed). Here is the code with all of the fixes:

I am trying to merge a Qr Code onto a pdf. When I split the code into two separate scripts it works fine. I am new to phython any help is appreciated. I am running this on RHEL 7.4 in Phyton 2.7 Yes I know it's old but it is a 3rd party server and I cannot upgrade it.
...ANSWER
Answered 2021-Apr-26 at 14:26Your error is saying that your own pyqrcode instance has no create function, which it does not. Also, best not to name a class with the same name as a module
You can fix that by importing the create function

QUESTION
I am using pyqrcode. I want to save the generated QR code to s3 bucket.
...ANSWER
Answered 2020-Oct-15 at 21:09Put your image file creation in a try/except first to see if it can create the file successfully. I did similar type of thing in the past, I saved the file to /tmp and then upload it there after.
So first check to make sure that your file is created and can save out locally to the lambda, it may be due to the location. Isolate out to see if it's the file creation problem or uploading problem.
QUESTION
This python / flask script creates an svg QR code byte stream but when I try to render it using a Jinja2 template {{ qr[0] }}, it renders as text. How can I render it as an image? As you can see from the code below, I have successfully transferred the data to the client - I do not need help with that - the only issue is that the data is in the wrong format - an svg byte stream - whereas I want to display that data as an image.
For the benefit of clarification, I MUST export the qr code in the render_template because I have other variables that contribute to the qr code, which also need to be exported. Therefore, the method does not work.
Likewise, I do not want the data to be visible in the URL.
...ANSWER
Answered 2020-Aug-18 at 19:58You've to decode the byte stream before usage in the template. Further you've to use Jinja's | safe filter.
