How can I use SciPy for numerical integration in Python?

You can use the scipy.integrate module for numerical integration. What specific function or method are you interested in?

I'm looking to integrate a simple function, like sin(x), over the interval from 0 to π.

You can use scipy.integrate.quad for that. Here's a quick example:

import numpy as np
from scipy.integrate import quad

result, error = quad(np.sin, 0, np.pi)
print(result)  # This should print 2.0

What does the quad function return?

The quad function returns two values: the integral result and an estimate of the absolute error in the result.

Can I integrate more complex functions with multiple variables?

Yes, for multiple variables, you can use scipy.integrate.nquad. It allows you to integrate functions of multiple variables.
