#36 , #14

Fix linting issues and refactor code for PEP 8 compliance ( except for the max length limit check, The PEP 8 guideline suggests a maximum line length of 79 characters for Python code, However, in practice, many projects and developers find this limit too restrictive for modern development environments. With wider screens and IDEs commonly setting default limits of 120 characters, it's common to see larger line length limits used in practice, typically around 100 or 120 characters. By allowing longer lines, code can often be more readable and maintainable, especially for function calls, method chains, or longer strings)

• Organized imports in the correct order.
• Refactored function and variable names to follow snake_case naming convention.
• Ensured class names start with a capital letter.
• Removed commented-out code to clean up the codebase.
• Applied PEP 8 formatting rules to ensure consistency.
• Addressed Pyflakes rules to fix any undefined names and other issues.
