SciPy — Introduction
What is SciPy?
SciPy is a Python library for scientific and technical computing. It builds on NumPy with additional modules for optimization, integration, interpolation, and more.
Key features
- Optimization: Minimization, curve fitting
- Integration: Numerical integration
- Interpolation: Data interpolation
- Signal processing: Filtering, transforms
- Linear algebra: Matrix operations
- Statistics: Statistical functions

Example
from scipy import optimize
import numpy as np
# Find minimum of a function
def f(x):
return (x - 2)**2 + 1
result = optimize.minimize(f, x0=0)
print(f"Minimum at x = {result.x[0]:.2f}")
print(f"Minimum value = {result.fun:.2f}")
