SciPy vs Other Python Libraries

1. SciPy vs NumPy

While NumPy handles array operations, SciPy builds on top of it to offer more specialized tools like statistical functions and solvers.

2. SciPy vs Pandas

Pandas is excellent for data manipulation, but lacks statistical and optimization tools. SciPy fills that gap.

3. SciPy vs Scikit-learn

Scikit-learn uses SciPy under the hood. SciPy is focused on scientific computing, while Scikit-learn is built for machine learning.
