Python and Julia: the best of friends?
summary
Argument: Julia gains speed from staged compilation, type stability and multiple dispatch and Python gains access to Julia’s fast non‑vectorized loops via pycall from a Jupyter notebook. Concrete demos include FFTs and an Asian option Monte Carlo where Julia code runs in a few seconds versus ~20+ seconds in Python (roughly 30× faster in showcased cases). Examples wire matplotlib, scipy/optimize and SymPy together, show delegation to array libraries, and measure actual wall‑clock timing and overflow/type behavior.
