 - Choose logical names when renaming on import. It is preferable to use standard names (e.g., `import pandas as pd`) or select logical shorter names (e.g., `import matplotlib as mpl`) when renaming on import.
 - Pay attention to possible name conflicts. When renaming imported modules or importing functions from modules, be careful that the names do not conflict with built-in Python functions (e.g., `import matplotlib as map` would conflict with the built-in Python function `map()`).
