Oct 27, 2021 · There are two approaches that can be used to connect MySQL and PHP code, which are mentioned below. Let’s get to know both of these options a bit more. A Database Abstraction Layer is the PHP Data Objects (PDO) extension.

For Data Analysts and Data Scientists, Python has many advantages. A huge range of open-source libraries make it an incredibly useful tool for any Data Analyst. We have pandas, NumPy and Vaex for data analysis, Matplotlib, seaborn and Bokeh for visualisation, and TensorFlow, scikit-learn and PyTorchfor machine learning applications (plus many, many...
Requirements & Installation
To code along with this tutorial, you will need your own Python environmentset up. I use Anaconda, but there are lots of ways to do this. Just google "how to install Python" if you need further help. You can also use Binder to code along with the associated Jupyter Notebook. We will be using MySQL Community Server as it is free and widely used in the industry. If you are using Windows, this guide will help you get set up. Here are guides for Mac and Linuxusers too (although it may vary by Lin...
Importing Libraries
As with every project in Python, the very first thing we want to do is import our libraries. It is best practice to import all the libraries we are going to use at the beginning of the project, so people reading or reviewing our code know roughly what is coming up so there are no surprises. For this tutorial, we are only going to use two libraries - MySQL Connector and pandas. We import the Error function separately so that we have easy access to it for our functions.
By this point we should have MySQL Community Serverset up on our system. Now we need to write some code in Python that lets us establish a connection to that server. Creating a re-usable function for code like this is best practice, so that we can use this again and again with minimum effort. Once this is written once you can re-use it in all of yo...
Now we're all set to start running SQL commands into our Server and to start building our database. The first thing we want to do is to create the necessary tables. Let's start with our Teacher table: First of all we assign our SQL command (explained in detail here) to a variable with an appropriate name. In this case we use Python's triple quote n...
Now we have a functional database to work with. As a Data Analyst, you are likely to come into contact with existing databases in the organisations where you work. It will be very useful to know how to pull data out of those databases so it can then be fed into your python data pipeline. This is what we are going to work on next. For this, we will ...
When we are maintaining a database, we will sometimes need to make changes to existing records. In this section we are going to look at how to do that. Let's say the ILS is notified that one of its existing clients, the Big Business Federation, is moving offices to 23 Fingiertweg, 14534 Berlin. In this case, the database administrator (that's us!) ...
It is also possible use our execute_query function to delete records, by using DELETE. When using SQL with relational databases, we need to be careful using the DELETE operator. This isn't Windows, there is no 'Are you sure you want to delete this?' warning pop-up, and there is no recycling bin. Once we delete something, it's really gone. With that...
We saw when populating our tables that we can use the SQL INSERTcommand in our execute_query function to insert records into our database. Given that we're using Python to manipulate our SQL database, it would be useful to be able to take a Python data structure (such as a list) and insert that directly into our database. This could be useful when ...
We have covered a lot of ground in this tutorial. We have learned how to use Python and MySQL Connector to create an entirely new database in MySQL Server, create tables within that database, define the relationships between those tables, and populate them with data. We have covered how to Create, Read, Update and Deletedata in our database. We hav...
In short, this extensions allows the Python interpretter to be embedded inside of PHP (think of PHP as the parent language with Python as its child). This allows native Python objects to be instantiated and manipulated from within PHP. There is also initial support for accessing PHP functions and data from within the embedded Python environment.
Dec 16, 2008 · the mysql-connecter-python is an open source Python library that can connect your python code to the MySQL data base in a few lines of code. And it is very compatible with the latest version of Python.
Mar 18, 2023 · Python MySQL Connector is a Python driver that helps to integrate Python and MySQL. This Python MySQL library allows the conversion between Python and MySQL data types. MySQL Connector API is implemented using pure Python and does not require any third-party library.
In this tutorial, you saw how to use MySQL Connector/Python to integrate a MySQL database with your Python application. You also saw some unique features of a MySQL database that differentiate it from other SQL databases.

Apr 26, 2021 · You can also write a Python code in C/C++ and compile it. Interpreted language: Python codes are executed line-by-line, one at a time similar to Java, C++, and C. Therefore, code compilation is unnecessary, making debugging easier and saves time.
