Issue Reporting Guideline

To maintain an effective bugfix workflow and make sure issues will be solved, I ask reporters to follow some simple guidelines.

Note

  • if any of the issue is not following the below template and guideline i will not facilitate that issue & will directly close.

Before creating an issue, please do the following:

  1. Use the GitHub issue search — check if the issue has already been reported.
  2. Check if the issue has been fixed — try to reproduce it using the latest master in the repository.
  3. Make sure, that information you are about to report is related to this repository and not the one available Python's repository, Because this repository cannot be downloaded via pip.

A good bug report shouldn't leave others needing to chase you up for more information. Please try to be as detailed as possible in your report. What is your environment? What was the course url? What steps will reproduce the issue? What OS experience the problem? All these details will help to fix any potential bugs as soon as possible.

Example:

Short and descriptive example bug report title

A summary of the issue and the OS environment in which it occurs. If suitable, include the steps required to reproduce the bug.

  1. This is the first step
  2. This is the second step
  3. Further steps, etc.

<url> - a udemy course link to reproduce the error.

Any other information you want to share that is relevant to the issue being reported.
