🔒 One scipy function or two numpy functions

[stone dew]

Hey guys! I have a doubt, in my code I am importing Scipy only to use cumulative_trapezoid. I could do this using only Numpy with cumsum and trapz (since I already import numpy for other functions). Which option is most recommended? Which is probably faster?

• Ask your Python question, not if you can ask or if there's an expert who can help.
• Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
• Explain what you expect to happen and what actually happens.

looks like that operation in scipy is entirely implemented via numpy, so it shouldn't make much of a difference (if any at all) besides the first import time
if you are already importing scipy in other files, it should be cached during that python execution and not take any time to import the second time onwards though

you could even just copy/paste that specific function into your file instead

google "Scipy cumulative_trapezoid" -> find docs -> "source" button:

https://github.com/scipy/scipy/blob/v1.14.1/scipy/integrate/_quadrature.py#L395-L495

if their implementation is more efficient than whatever you were planning, their version may be faster though :p

Personally, and naively, I'd go with the scipy one. They should have thought about efficient use of the numpy functions, assuming there's much or any choice about how to use it.
