Make sure you follow along!I am using Juyptr Notebook here, so the Image and Audio CAPTCHA will be created in the same folder where my python file is located. Time to code!You can find the code at my GitHub Repository.
I am using hello17world as our text here. We will use the generate method to do the same.We will call generate method on our image and store this inside data. Image = ImageCaptcha(width = 280, height = 90)Next, let's generate the characters or numbers which will be displayed in the CAPTCHA. We can also specify image dimensions like its height or width.

It will be created in png format. Data = image.generate( 'hello17world')At last, let's write it in a file using the following command.
Audio = AudioCaptcha()Next, let's generate the numbers which will be used in the Audio CAPTCHA. Moving forward, we will now store it and call it as audio. From captcha.audio import AudioCaptchaIf it runs successfully, you are good to go.
If you have any Queries or Suggestions, please reach out to me in the Comments Section below. Write( '789', 'demo2.wav')I hope this helped you in understanding how to create your own Image and Audio CAPTCHA. It will be created in wav format. Data = audio.generate( '789')At last, lets write it in a file using the following command.
