We’ll pass either a number or a variable into the parentheses of the method and then that numeric value will be converted into a string value. We can convert numbers to strings through using the str() method. Strings are a common form of data in computer programs, and we may need to convert strings to numbers or numbers to strings fairly often, especially when we are taking in user-generated data. Converting with StringsĪ string is a sequence of one or more characters (letters, numbers, symbols). Read “ Python 2 vs Python 3: Practical Considerations” for more information about the differences between Python 2 and Python 3. In Python 2, since you were dealing with two integers, you would receive an integer back as your answer, instead: 5 / 2 = 2. To use this function, add an integer inside of the parentheses: Python’s method float() will convert integers to floats.
Python has built-in methods to allow you to easily convert integers to floats and floats to integers. Sometimes you are working on someone else’s code and will need to convert an integer to a float or vice versa, or you may find that you have been using an integer when what you really need is a float. In Python, there are two number data types: integers and floating-point numbers or floats.
If you don’t have a programming environment set up, you can refer to the installation and setup guides for a local programming environment or for a programming environment on your server appropriate for your operating system (Ubuntu, CentOS, Debian, etc.) Converting Number Types You should have Python 3 installed and a programming environment set up on your computer or server. This tutorial will guide you through converting numbers, strings, tuples and lists, as well as provide examples to help familiarize yourself with different use cases. For example, we may need to concatenate numeric values with strings, or represent decimal places in numbers that were initialized as integer values.
When programming, there are times we need to convert values between types in order to manipulate values in a different way. In Python, data types are used to classify one particular type of data, determining the values that you can assign to the type and the operations you can perform on it.
