What distinguishes `str` from `repr` in Python?

The distinction between str and repr in Python is rooted in their intended purposes when representing string output. The str function is designed to produce output that is easy for humans to read and understand. It aims to present information in a format that is clear and user-friendly, making it suitable for display to end-users.

On the other hand, the repr function focuses on providing an unambiguous representation of an object that is more suitable for developers and debugging purposes. The output from repr is often more formal, and in many cases, it aligns with how the object would be recreated in code. For instance, calling repr on a string returns the string with quotes, which can be helpful for indicating that it is a string type.

This differentiation is significant when working with data and representations in Python, as it helps contextually tailor output according to the audience—be it a developer or an end-user. Thus, understanding this distinction is crucial for effective programming and debugging in Python.
