Is database is an essential thing for DataScience?
Yes, It is an essential thing. Without the data, the data analysis and forecasting can’t be done. Right!. The data can be any kind of format that may be in CSV, XLS. Consider the retail organization selling their multiple products from the past 5 years. The company decided to forecast the prediction of sales for the next two years.
I grasped what you thinking? Basically, try the data export to CSV file. That can be easily handled in the pandas data frame. But the things not working in such way because prediction does not rely on a single table. It depends on multiple tables say transaction, sales, customer review, the revenue of product from 5 years those need to look in to determine the prediction. The best-opted way will be directly importing the table to the data frame. That will be easier for analysis data against all perspectives.
To connect MySQL using pandas, need to install package ‘mysql-connector-python’ as below command.
pip install mysql-connector-python
Package installation console
import mysql.connector as connection import pandas as pd try: mydb = connection.connect(host="localhost", database = 'Student',user="root", passwd="root",use_pure=True) query = "Select * from studentdetails;" result_dataFrame = pd.read_sql(query,mydb) mydb.close() #close the connection except Exception as e: mydb.close() print(str(e))

In this post, we will learn about pandas’ data structures/objects. Pandas provide two type of data structures:- ### Pandas Series Pandas Series is a one dimensional indexed data, which can hold datatypes like integer, string, boolean, float...
Basic Dataframe Manipulation using Pandas. Pandas DataFrames make manipulating your data easy, from selecting or replacing columns and indices to reshaping your data.
In this Pandas Tutorial, we will learn to insert/add a new row to an existing Pandas Dataframe. We will use pandas.DataFrame.loc, pandas.concat() and numpy.insert(). Using these methods you can add multiple rows/lists to an existing or an empty...
