This example demonstrates basic Python syntax and output within a Jupyter notebook, showing how simple print statements and expression evaluations behave. It highlights the classic floating-point precision issue where `0.1 + 0.2` does not equal `0.3`, and contrasts that with an epsilon-based comparison that returns `True`. The code also illustrates string handling with triple-quoted multiline strings and the difference between echoing a value and using `print()`. No external visualization libraries are used; the focus is purely on language fundamentals.
