I am looking to create Python classes that read a specific schema from any database. I will provide you the scheme, it contains about 23 tables. The classes must be able to read from an H2 database. The data is read on every invocation of a method that reads a particular table. The method will load the data into a pandas DataFrame and return it. In addition, I am looking for charting capabilities using matplotlib. There will be 5 charts that will need to be created using data from these 23 tables. This will be packaged as an importable library. We'll call this library pycordence. Here is some representative Python code on how these classes should work. Imagine there are 15 tables, TABLE1..TABLE15 import pycordence node = Node (url,username,password) # Connects to a database df = node.get_table1() # Retrieves the data from TABLE1, puts it into a DataFrame and returns print(df) df = node.get_table2() #Does same for TABLE2... node.display_stat1() # Displays a matplotlib chart using data from the 23 tables Requirements: - Must use Python 3, latest version major / minor version - Adhere to well established Python naming conventions - Must use pandas. Additional SQL libraries are allowed (i.e. SQLAlchemy, NumPy) but methods must return DataFrames - Must connect to H2 database (I found this to not be easy, Postgres drivers may fail) - Must be packaged so that it can be rolled out and pip'd by others - All source code must be documented completely - A README must be provided with notes on how to use, any potential issues I will provide the database schema after I select the right person for this job.

Hi, I am a Computer Engineer and a Full Stack Django Developer with an extensive experience of 5 years in development. I am an expert in Web Scraping, and develop scrapers in Python Programming Language. Unlike some developers who scrape data using GUI tools, I will develop scrapers in Python language using Requests and LXML modules, and will make the code completely robust and reliable by adding all the exceptional handling codes required. I can also develop an API for the scrapers, so that you can implement the code in whatever programming language you are using for your backend. Please reply, so that we can discuss this further. Thanks
