Today we will discuss the different kinds of number variables in Python. How to interact with them, and what they are used for. There are four kinds of numbers in the python language: Int Long Float Complex Integers Integers are the basic kinds of numbers in any programming language. Integers are whole numbers, which means they do not have a decimal point. They can be either positive or negative. In Python 2 there is a maximum int size of 9223372036854775807. You can see this Read more […]

When you read a date or time from a text file, user input, or a database, you are likely to get the date information as a string. It is helpful to convert the string to a datetime object since it will allow you to do more advanced functions. In todays article I will discuss and show examples of datetime objects in python. Specifically, I will show how to convert a string to a datetime, how to compare and reformat datetime variables, how to work with timezones, and how to extract specific bits of Read more […]

Understanding the Python Math Operators is very important. You use these operators throughout the Python language whether it be concatenating strings, doing basic algebra, complex calculus, or delving into data science. In this article, we will cover the basics of doing math with python including how to do multiplication, division, addition subtraction, exponents, and orders of operation. What is an Operator? A math operator is a symbol that defines a specific kind of logic. For example, if Read more […]

A string is one of the many data types in Python. Some of the other common ones are objects, lists, integers, and dates. At its core, a string is really a list/array of characters. Today we will be Python String Operations. We will cover how to Concatenate, Tokenize, Manipulate, Search strings, and create string templates. Concatenate Concatenating strings is just taking two separate strings and gluing them together. In Python, it is extremely easy. You simply use the ‘+’ symbol to add the strings Read more […]

Did you know you can host a webpage using nothing but Python code? You don’t have to use things like IIS or Apache. While you may not get all of the same features. When you are trying to write a simple application. Or if you want to host an API, this route is an option for you. In this article, I will describe how to create a basic webpage using Python and Flask. Prerequisites To follow this tutorial, you need the following three prerequisites: install Python 3 Install Pip Install Read more […]

In this article we will discuss error handling using Python With Statements Try/Except/Finally statements, show how to use these in combination, and compare how it works to try/catch code blocks in other languages. What is error handling? Error handling is when you put in some extra code to tell your script what to do when things don’t go totally to plan. perhaps you try to open a file that isn’t there. Or perhaps a user puts in unexpected input. Without any error handling, your program Read more […]
