flake8/.flake8 (1)
1-3: LGTM! Standard flake8 configuration for modern Python development.The configuration uses sensible defaults with 88-character line length and ignores E203/W503, which align well with black formatter usage.

🛠️ Refactor suggestion
Add proper spacing in function call.
The function call needs proper spacing after the comma.

+my_function(1, 2)📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

🤖 Prompt for AI Agents
In flake8/example.py at line 16, the function call my_function(1,2) lacks proper
spacing after the comma. Add a space after the comma so it reads my_function(1,
2) to comply with spacing conventions.

🛠️ Refactor suggestion
Fix function signature spacing and print statement formatting.
The function contains multiple spacing violations that flake8 catches.

In flake8/example.py around lines 3 to 4, fix the spacing issues in the function
signature by removing extra spaces before the parameters and after the opening
parenthesis. Also, adjust the print statement to have proper spacing after
commas and around operators to comply with flake8 rules.

🛠️ Refactor suggestion
Apply Python naming conventions and fix indentation.
The class violates PEP 8 naming conventions and has inconsistent indentation.

In flake8/example.py around lines 6 to 8, rename the class to use CapWords
convention (e.g., MyClass) and fix the indentation to use consistent spaces
(typically 4 spaces per indentation level). Also, add a space around the
assignment operator in the __init__ method to comply with PEP 8.

🛠️ Refactor suggestion
Remove unused imports for cleaner code.
The static analysis tools correctly identify that both os and sys imports remain unused in this file.

In flake8/example.py around lines 10 to 14, rename the method from doSomething
to do_something to follow snake_case naming conventions. Remove unnecessary
spaces inside parentheses and after keywords, and ensure consistent indentation
throughout the method. Adjust spacing around operators and after commas to
comply with PEP8 style guidelines.
