Mathematical and Statistical Methods A set of mathematical functions that compute statistics about an entire array or about the data along an axis are accessible as methods of the array…
Universal Functions: Fast Element-Wise Array Functions A universal function, or ufunc, is a function that performs element-wise operations on data in ndarrays. You can think of them as fast vectorized…
Boolean Indexing Let’s consider an example where we have some data in an array and an array of names with duplicates. I’m going to use here the randn function in…
Basic Indexing and Slicing NumPy array indexing is a rich topic, as there are many ways you may want to select a subset of your data or individual elements. One-dimensional…
NumPy Basics: Arrays and Vectorized Computation NumPy, short for Numerical Python, is one of the most important foundational packages for numerical computing in Python. Most computational packages providing scientific functionality…
