How create bar chart race with python
Recently, I come across a medium post on announcement off Official Release of bar_chart_race by Ted Petrou. In his article, he provides an excellent tutorial on how to create Bar Chart Race using bar_chart_race package. Check out the official document here . In our example we use a World Population from 1955 to 2020 dataset from kaggle or you can directly download dataset here . Installation of Bar Chart Race package pip3 install bar_chart_race pandas or using anaconda:

How Make Cutest Hand Drawn Charts in Python

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 . Different from the common charts such as Matplotlib and seaborn, this package can be used to generate the following kinds of charts that look like hand drawn, and the effect may be better in some scenarios. Cute charts are also interactive and dynamic. Whenever the mouse is hovering on the chart, the numbers show up.

Advanced SQLAlchemy Features You Need To Start Using

Advanced SQLAlchemy Features You Need To Start Using
If you are Python developer and you work with SQL databases, then SQLAlchemy is most likely a library you are familiar with. It’s a powerful, yet flexible toolkit for working with SQL in Python with lots of features. Some of these features like ORM and basic queries are common knowledge, but there are quite a few features you might not know about and should definitely be taking advantage of. So, let’s se how to leverage things like hybrid properties, nested queries, table metadata, dialects and more!

How use Python retry decorator function with API
An ever-increasing proportion of a typical company’s infrastructure is moving to the cloud. More companies are shifting towards a micro-service approach. These paradigm shifts away from local to cloud-based means that you probably also have faced a situation where you had to pull data from somewhere or write data somewhere that is not your local computer. 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.

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?

How Control Object Attributes In Python

How Control Object Attributes In Python
Private methods and attributes in Python Unlike Java, which enforces access restrictions on methods and attributes, Python takes the view that we are all adults and should be allowed to use the code as we see fit. Nevertheless, the language provides a few facilities to indicate which methods and attributes are public and which are private, and some ways to dissuade people from accessing and using private things. Normal attribute access Let’s take a look at how normal attribute access works.

How Solve Any Linear Equation in python

How Solve Any Linear Equation in python
This function can solve any linear equation in three lines of code — it could even be rewritten in two lines. As of my knowledge, this is the most efficient method to solve a linear equation in Python. def solve_linear(equation,var='x'): expression = equation.replace("=","-(")+")" grouped = eval(expression.replace(var,'1j')) return -grouped.real/grouped.imag solve_linear('x - 6 = 10') 16.0 solve_linear('x*1/2 - 6 = 10') 32.0 How does it work? First, let’s define what a linear equation is — it must be solvable in its pure form.

Learn How to do 3 Advanced Excel Tasks in Python
Excel is the ubiquitous data analysis tool — it’s easy to pick up, mostly everyone has a copy of it, and it’s quite powerful once you get the hang of it! Meanwhile, Python is often regarded as a bit more challenging to pick up, but as having limitless potential. In this post, we’ll explore three things you can easily do in Python that you normally do in Excel! Setup For debian based distro you must install python pandas and xlrd packages first:
