Code Quality Improvements Based on Pylint Report

[marcfreir]

Hello, Markus Siemens & TinyDB team!

I ran a Pylint analysis on the TinyDB codebase, and I identified some areas where code quality could be improved. Below is a summary of the findings, of the code block for the function def __repr__(self), along with suggestions for addressing each category. These changes should enhance code readability, maintainability, and adherence to Python's best practices.

Enhanced f-String Usage:

• Issue: The __repr__ method uses .format(), which can be less readable than f-strings.
• Suggestion: Replace .format() with f-strings. For example:

  # Current:
  args = [
      'tables={}'.format(list(self.tables())),
      'tables_count={}'.format(len(self.tables())),
      'default_table_documents_count={}'.format(self.__len__()),
      'all_tables_documents_count={}'.format(
          ['{}={}'.format(table, len(self.table(table))) for table in self.tables()]
      ),
  ]
  # Suggested:
  args = [
      f'tables={list(self.tables())}',
      f'tables_count={len(self.tables())}',
      f'default_table_documents_count={self.__len__()}',
      f'all_tables_documents_count={[f"{table}={len(self.table(table))}" for table in self.tables()]}',
  ]

And thanks for the awesome project!
