Why Numpy Arrays over Lists ? Let’s learn & explore in detail why can’t we use Python Lists & instead switch to Numpy Arrays for Data Science Related stuff.
Let’s start with how this exploration started. We were studying with one of our Trainer & he told us Numpy is faster than Lists and you shouldn’t go deep into the details.
But as you all know 😃our Mind is opposite, _** The thing which is asked not to do we do it first, So this was the Motivation to go into details of the Topic._**
First attempt :-
This was not that great & I found that most of the Operations which can be performed in Lists can also be done in Numpy Arrays.
Learn about NumPy Array, NumPy Array creation, various array functions, array indexing & Slicing, array operations, methods and dimensions,It also includes array splitting, reshaping, and joining of arrays. Even the other external libraries in Python relate to NumPy arrays.
The content present in the NumPy arrays can be made accessible, and also we can make changes thorough indexing as we got to know in the previous module. Another way of data manipulation in arrays in NumPy is though slicing through the arrays. We can also try changing the position of the elements in the array with the help of their index number. Slicing is the extension of python’s basic concept of changing position in the arrays of N-d dimensions.
NumPy Releases First Review Paper On Fundamental Array Concepts. The library adds support for large, multi-dimensional arrays as well as matrices, and brings the computational power of languages like C and Fortran to Python.
Numpy is a python library used for computing scientific/mathematical data.
Learn to create arrays using NumPy in Python. The Numpy Array Creation of different dimensions has been illustrated with the help of examples. NumPy focuses on working with a multi-dimensional array, and these are those arrays that have more than two dimensions. These multidimensional arrays also are known as matrices. The functions that we can implement on these are traverse, insertion, deletion, search and update.
