How Make Cutest Hand Drawn Charts in Python

In this tutorial, I would like to introduce a very cool Python hand-painted style visualization package: cutecharts .

On a small scale, there rarely are problems around that. If some extraction or writeback fails, you would typically notice that and would be able to remedy the mistake. But, as you move towards larger-scale operations and potentially hundreds of thousands of transactions, you don’t want to get screwed over by a temporary drop of internet-connection, too many concurrent writes, a temporarily unresponsive source system, or god knows what else.

How to Create Fake Data with Faker

How to Create Fake Data with Faker
Faker is an open-source python library that allows you to create your own dataset i.e you can generate random data with random attributes like name, age, location, etc. It supports all major locations and languages which is beneficial for generating data based on locality. Let's say you want to create data with certain data types (bool, float, text, integers) with special characteristics (names, address, color, email, phone number, location) to test some Python libraries or specific implementation. But it takes time to find that specific kind of data. You wonder: is there a quick way that you can create your own data?

7-bit ASCII Character Codes

7-bit ASCII Character Codes
The ASCII table, an abbreviation for American Standard Code for Information Interchange, utilizes a 7-bit character encoding system to represent 128 unique characters. These include both control and printable characters. The table is composed of 32 control characters (ranging from 0-31) used for text formatting management, and 96 printable characters (ranging from 32-127). The latter includes the English alphabet, digits, and common punctuation marks.
