![]() Solution 1: Divide Each Number in the Range This means you cannot have a range() call like this: numbers = range(0.1, 1.0)Ī call like this would produce an error that warns you about misusing the range() function. However, the range is supposed to consist of integers only. In Python, the built-in range() function can be used to generate a range of values between m and n. Problem: Python range() Function Doesn’t Work with Floats In this guide, you will see some alternative approaches to creating a range of floats in Python. Once you have these key concepts down, test your knowledge in Lesson 04: Coding Exercise.To create a range of floats in Python, use list comprehension.įor example, to create a range of floats from 0 to 1 with a 1/10th interval: rng = In addition to this, you will very often in loops need to identify Comparison Operators (equal to, less than, etc). ![]() Floor // #This will return the max number of times two numbers can be divided into each other, e.g.Modulo % #This will return the remainder, e.g.Throughout your DH project, you will very likely need to manipulate numbers through mathematical operations. In all of these cases, these functions take a single argument, the item that you want to convert. I will explain this process in future lessons, but for now, you should know how to do it. This is particularly useful when you are trying to create files based on the number of iterations in a loop. In some instances, you may need to convert an integer or a float to a string. ![]() In this case, the integer will receive a. We can similarly change an integer to a float using the float() function. When we do this, the float will lose its decimal and the numbers behind the decimal place. If we want to change a float to an integer, we can do so using the int() function. If it does not, it will automatically consider it an integer. If your number has a decimal, Python will automatically consider it a float. ![]() The way in which you create a number object in Python is the to create an object name, use the equal sign and type the number. Further, numbers are essential to understand for performing more advanced functions in Python, such as Loops, explored in Lesson 09. What if you want to know the times a specific author wrote to a colleague or to which places he wrote most frequently, as was the case with the Republic of Letters project at Stanford? In order to perform that kind of analysis, you MUST have a command of how numbers work in Python, how to perform basic mathematical functions on those numbers, and how to interact with them. This is am important distinction that you MUST remember, especially when working with data imported from and exported to Excel.Īs digital humanists, you might be thinking to yourself, “I just work with text, why should I care so much about numbers?” The answer? Numbers allow us to form quantitative analysis. As noted in Lesson 02, integers are numbers without a decimal point, whereas floats are numbers with a decimal point. Numbers in Python exist in two chief forms: integers and floats. Now that you understand how strings work, let’s begin exploring another type of data: numbers.
