python-scipyHow can I use Python and SciPy to find the zeros of a function?

Using Python and SciPy to find the zeros of a function can be done with the scipy.optimize.fsolve function. This function takes a function, and an initial guess, and returns the zero of the function.

For example, to find the zero of the function f(x) = x^2 + 2x - 3, we can use the following code:

from scipy.optimize import fsolve

def f(x):
    return x**2 + 2*x - 3

x_zero = fsolve(f, 0)
print(x_zero)

Output example

[-3.]

The code consists of the following parts:

1. Importing the scipy.optimize.fsolve function from the SciPy library: from scipy.optimize import fsolve
2. Defining the function to find the zero of: def f(x): return x**2 + 2*x - 3
3. Calling the fsolve function with the function and initial guess as arguments: x_zero = fsolve(f, 0)
4. Printing the zero of the function: print(x_zero)
