  Building RESTful APIs with Flask in PyCharm  Installing packages Once your virtualenv is ready, click the “Install” button to begin installing packages. We’ll be installing three packages for our project: Flask  (install either by pycharms STTINGS-----PYTHON INTERPRETOR (+)) Flask-Restless  (for building the RESTful API) Flask-SQLAlchemy  (for connecting to our database) || OR  MySQLdb In Pycharms (Main.py):write below code here change parameters as per your database: import flask from flask import Flask, json, request, jsonify from flask_mysqldb import MySQL, MySQLdb # pip install flask-mysqldb https://github.com/alexferl/flask-mysqldb app = Flask(__name__) app.secret_key = "2021" app.config[ 'MYSQL_HOST' ] = 'localhost' app.config[ 'MYSQL_USER' ] = 'root' app.config[ 'MYSQL_PASSWORD' ] = '' app.config[ 'MYSQL_DB' ] = 'entry_system' app.config[ 'MYSQL_CURSORCLASS' ] = 'DictCursor' mysql = MyS

 Python Pandas As Json Pandas allows us to analyze big data and make conclusions based on statistical theories. Pandas can clean messy data sets, and make them readable and relevant. Pandas gives you answers about the data. Like: Is there a correlation between two or more columns? What is average value? Max value? Min value? Pandas are also able to delete rows that are not relevant, or contains wrong values, like empty or NULL values. This is called  cleaning  the data. Installation of Pandas If you have Python and PIP already installed on a system, then installation of Pandas is very easy. (c) 2019 Microsoft Corporation. All rights reserved. C:\Users\RCF>cd..

 Install WAMP + PYTHON Integration I'd be glad to assist you with installing WAMP server to run Python. However, it's important to note that WAMP is primarily designed for running PHP applications, and Python typically has its own dedicated environments like Anaconda or virtual environments. Important Considerations: WAMP's Primary Purpose: WAMP is primarily designed for running PHP applications. Using it for Python might not be the most optimal or efficient approach. Dedicated Python Environments: For dedicated Python development, consider using Python-specific environments like Anaconda or virtual environments. These environments provide better control over Python versions and packages. Web Framework Choice: If you need to run Python web applications, carefully evaluate the features and requirements of different web frameworks to choose the best one for your project. How to set up wamp to run Python programs and php on your own computer. SQL works also. Only tested on
