What are the differences between NumPy arrays and Python lists?
The question is about Python Numpy .
NumPy arrays have a fixed data type for every item, whereas Python lists can hold any data type. NumPy arrays are much faster for number crunching, use less memory, and allow calculations over entire arrays at once. Python lists are more flexible but slower; they require loops even for simple maths and aren’t designed for multi-dimensional data.
