Python List Append VS Python List Extend 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. python list append() Syntax and Arguments To call the append() method, you will need to use this syntax: python list append() From Left to Right: The list that will be modified. This is usually a variable that references a list Python Development
Python Sorting Libraries and Algorithms Benchmark/Comparison Sorting data is a basic task for data scientists and data engineers. Python users have a number of libraries to choose from with built-in, optimized sorting options. Some even work in parallel on GPUs. Surprisingly some sort methods don’t use the stated algorithm types and others don’t perform as expected. Choosing which library and type of sorting algorithm to use can be tricky. Implementations change quickly. As of this writing, the Pandas documentation isn’t even up to date with the code (although my PR updating the sort options was just accepted). Python Development
Top 5 sorting algorithms with Python code Sorting is a skill that every software engineer and developer needs some knowledge of. Not only to pass coding interviews but as a general understanding of programming itself. The different sorting algorithms are a perfect showcase of how algorithm design can have such a strong effect on program complexity, speed, and efficiency. sorting algorithms complexity Let’s take a tour of the top 6 sorting algorithms and see how we can implement them in Python!

Helpful Python Snippets That You Can Learn in 60 Seconds or Less Python represents one of the most popular languages that many people use it in data science and machine learning, web development, scripting, automation, etc. Part of the reason for this popularity is its simplicity and easiness to learn it. If you are reading this, then it is highly likely that you already use Python or at least have an interest in it. In this article, we will briefly see 30 short code snippets that you can understand and learn in 30 seconds or less. Development Python
Python DocStrings, Annotations and PEP8 Docstrings in Python Python Docstring is the documentation string which is string literal, and it occurs in the class, module, function or method definition, and it is written as a first statement. Docstrings are accessible from the doc attribute for any of the Python object and also with the built-in help() function can come in handy. One-line Docstrings The one-line Docstrings are the Docstrings which fits all in one line. Python Development
Python3 f-Strings and string formatting syntax As of Python 3.6, f-strings are a great new way to format string. Not only are they more readable, more concise, and less prone to error than other ways of formatting, but they are also faster! f-string Magic Simple Syntax: The syntax is similar to the one you used with str.format() but less verbose. Look at how easily readable this is: >>> name = "Eric" >>> age = 74 >>> f"Hello, {name}. Development Python
What’s __init__ for me? Python modules Modules in Python are simply Python files with a .py extension. The name of the module will be the name of the file. A Python module can have a set of functions, classes or variables defined and implemented. It is usually a good idea to split code into smaller modules for a couple of reasons. Primarily, modules can contain all of the code related to a particular coherent topic (e. Development Python
Building Python Real World Application - part 01 - Interactive Dictionary The first application we are going to build is a dictionary. An interactive dictionary. Now, what the dictionary will do? It will retrieve the definition for the word which user has entered, that’s what dictionaries do, right? In addition to that, if the user has made a typo while entering a word, our program will suggest the closest word saying ‘did you mean this instead?’, and if the word has more than one definition, retrieve all of them.

Python Sorting In this article, we explore the various techniques for sorting data using Python. Python Development
Python Dictionaries and JSON This week we will have a quick look at the use of python dictionaries and the JSON data format. After reading this post, you should have a basic understanding how to work with JSON data and dictionaries in python. I'll choose this topic because of some future posts about the work with python and APIs, where a basic understanding of the data format JSON is helpful. Python Development
Python String Formatters Python's str.format() method of the string class allows you to do variable substitutions and value formatting. This lets you concatenate elements together within a string through positional formatting. This tutorial will guide you through some of the common uses of formatters in Python, which can help make your code and program more readable and user friendly. Python Development
How To Use *args and **kwargs in Python 3 *args and **kwargs I have come to see that most new python programmers have a hard time figuring out the *args and **kwargs magic variables. So what are they ? First of all let me tell you that it is not necessary to write *args or **kwargs. Only the * (asterisk) is necessary. You could have also written *var and **vars. Writing *args and **kwargs is just a convention. Python Development
