What details must be specified when reporting a found error?

When reporting a found error in Python (or in a bug report in general), it is important to include the following details:

• Error description: what exactly happens, the expected and actual results.
• Steps to reproduce: a sequence of actions to repeat the error.
• Python version and libraries used: to understand the environment context.
• Operating system and its version: sometimes errors depend on the platform.
• Code or minimal example causing the error: to quickly verify the problem.
• Error messages and stack traces: full exception logs.
• Additional details: environment settings, environment variables, configuration files, if they influence.

Example:

Error: an exception ValueError occurs when calling the function foo().

Steps to reproduce:
1. Run the script example.py
2. Call foo(42)

Environment:
- Python 3.9.7
- OS: Ubuntu 20.04
- Libraries: requests 2.25.1

Trace:
Traceback (most recent call last):
  File "example.py", line 10, in <module>
    foo(42)
  File "example.py", line 5, in foo
    raise ValueError("Invalid value")
ValueError: Invalid value

Such a detailed report helps to understand and fix the error faster.
