Right Answer:
Backward compatibility is important because it allows users to run older code without modification. This is crucial for maintaining existing applications and systems, ensuring that updates do not break functionality.
Right Answer:
The design for readability in Python makes the language more accessible to beginners and promotes good coding practices. This leads to easier collaboration among developers and simplifies maintenance of code.
Right Answer:

Right Answer:
Python's interpreted nature allows for quick iteration and prototyping, which is invaluable in research and development phases. Developers can test and modify their code on the fly without the need for a separate compilation step.
Right Answer:
Python's clear and straightforward syntax contributes to its popularity, as it lowers the barrier to entry for new programmers. The ease of learning and using Python encourages more people to adopt it for various programming tasks.
Right Answer:
