What are the differences between PyPy and CPython ecosystems?

What are the main differences between PyPy and CPython?

PyPy is an alternative implementation of Python that focuses on speed and efficiency, while CPython is the standard implementation. PyPy uses a Just-In-Time (JIT) compiler to improve performance, whereas CPython interprets code line by line.

How does the ecosystem of libraries differ between the two?

CPython has a larger ecosystem with more libraries and frameworks available, as it has been around longer. PyPy is compatible with many CPython libraries, but some may not work optimally due to differences in implementation.

Are there any specific use cases where PyPy outperforms CPython?

Yes, PyPy tends to outperform CPython in long-running applications and scenarios that involve heavy computation, thanks to its JIT compilation.

What about memory usage? Is PyPy more efficient?

PyPy can be more memory efficient in certain cases, especially with long-running processes, but it may use more memory for short-lived processes compared to CPython.
