What are Panda and NumPy in data analytics?
Data Analytics is one of the important departments of our IT sector. Everything needs to be analyzed to predict some certainty about the upcoming in the market. Analysis plays a crucial role in balancing the nature of the company. The analysis is done using Python and machine learning. It requires some algorithm to perform tasks.
Sometimes these algorithms become so difficult to understand. Python had launched two libraries to make the calculation simpler - NumPy and Panda. NumPy and Panda are the two key packages of python. NumPy increases the functionality of python by creating multi-dimensional array objects. It uses a large set of mathematical functions for quick entries of the array without the need for loops.
What is NumPy?
NumPy means 'Numerical Python' or 'Numeric python'. It provides fast mathematical computation for matrices and arrays. Machine Learning ecosystem has two essential parts - Arrays and Matrices. NumPy along with Machine Learning modules like sci-kit- learn, TensorFlow, Pandas are included in the Python Machine Learning ecosystem. You can learn more about NumPy by joining the Data Analytics training. But first, we have to know a short description of NumPy.
It helps in solving multidimensional array-oriented computing functionalities designed for high-level mathematical and scientific computations. NumPy can be imported using
>>> import numPy as np
NumPy's mainly deals with homogeneous multidimensional-array. This table contains same type of elements like strings or integers. Dimensions in NumPy are called axes. The count of axes is called a rank. Some ways to create an array in NumPy like np.zeroes, np.ones, np.array, etc.
NumPy has some important attributes like:
1. Ndim: displays the dimension of the array
2. Shape: returns a tuple of integers indicating the size of the array
3. Size: returns the total number of elements in the NumPy array
4. Dtype: returns the type of elements in the array, i.e., int64, character
5. Itemsize: returns the size in bytes of each item
6. Reshape: Reshapes the NumPy array
What is Pandas?
Exactly as NumPy, Panda is also one of the most widely used libraries in data science. It provides high-performance in complex calculations, easy to use structures and data, and data analysis tools. Panda provides objects for 2-dimensional arrays in a 2-d memory table called data frames. It looks like a spreadsheet with rows and columns.
Panda is also capable of plotting to provide additional functionalities like pivot tables, computing columns based on other columns, and plotting graphs. One can also import Panda into Python using-
>>> import pandas as pd
Some data structures in pandas are:
1. Series object: 1d object,
2. Dataframe objects: 2d table
3. Panel objects: Dictionary of Dataframes
Using pd.series function, panda series can be created. Panda also provides the basic mathematical functionalities like addition, subtraction, multiplication, division, conditional operations, and broadcasting. Like an array, each row is provided with an index number and starting with 0.
Data frames of Panda represent a spreadsheet with cells, rows, and columns. Rows and Columns of Dataframe are simple and intuitive into access. It also provides SQL functions like to filter, sorting of rows, etc. For example-
>>> people_dict = { "weight": pd.Series([68, 83, 112],index=["alice", "bob", "charles"]), "birthyear": pd.Series([1984, 1985, 1992], index=["bob", "alice", "charles"], name="year"),
"children": pd.Series([0, 3], index=["charles", "bob"]),
"hobby": pd.Series(["Biking", "Dancing"], index=["alice", "bob"]),}
>>> people = pd.DataFrame(people_dict)
>>> people
You can learn more about NumPy and Panda during the Data Analytics course. It is the most desirable course of this decade. Over 5000 job vacancies for Data Analysts are available in India. It is also one of the highest paying jobs in India. If you are passionate and interested about this career profile, you should take Data Analytics training from a well-known institute. Choosing a good institute is also a big challenge in this competitive era.
