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. 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

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

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.

Python List or any Iterable Comprehension

Sometimes a programming design pattern becomes common enough to warrant its own special syntax. Python’s are a prime example of such a syntactic sugar. List comprehensions in Python are great, but mastering them can be tricky because they don’t solve a new problem: they just provide a new syntax to solve an existing problem. Let’s learn what list comprehensions are and how to identify when to use them.

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!

Python Pandas Cheat Sheet

Being able to look up and use functions fast allows us to achieve a certain flow when writing code. So I’ve created this cheatsheet of functions from python pandas. This is not a comprehensive list but contains the functions I use most, an example, and my insights as to when it’s most useful.

Python List Append VS Python List Extend

If you want to learn how to work with python list append() and list extend() and understand their differences, then you have come to the right place. They are powerful list methods that you will definitely use in your Python projects.

Python list.append()

Let's see how the append() method works behind the scenes.

You should use this method when you want to add a single item to the end of a list.
