Lock if the called function relies a lot on Python objects. "threading" is mostly useful when the execution bottleneck is a compiled extension that explicitly releases the GIL (for instance a Cython loop wrapped in a "with nogil" block or an expensive call to a library such as NumPy). ...

Since then, the NumPy package has found wide-spread adoption in academia and industry. Today, NumPy is one of the core packages for numerical computation in Python. NumPy provides a powerful multi-dimensional array object with advanced and efficient general-purpose array operations. Additionally, ...
