The method of reading data from a file is handled with the open() and close() functions. Introducing the open() and close() Functions I’ll be demonstrating on Ubuntu Linux, but all you’ll need to change is the tool you use for creating new text files. With such an application, you would only need to edit the source file to then add more entries to the save-to file.Īs with all of the articles in this series, you’ll need Python installed (which can be used on Linux, macOS, or Windows). Say, for example, you create a small program that reads data from one file and saves it a sort of database of information. This is a very simple concept to understand and the application of it can really help you grow as a Python programmer.īut what type of implications does reading a file with Python have? What can you use it for? I want to introduce you to yet another very handy feature of Python, the ability to open external files and read them. With enough skill and creativity, you can make this language do quite a bit. One of the things I hope you’ve grown to understand is just how easy Python is to learn as well as how useful it can be. All of these entries should add together to help you understand the basics of Python as well as some fundamental concepts of programming in general. So far we’ve learned about data types, the range() function, and/or operators, functions, saving input to a file, the python console, and what makes Python special.
#PYTHON ON MAC FOR BEGINNERS SERIES#
Our goal with this series is to make the Python language easy to learn and use. We’re back with more Python goodness from a beginner’s perspective.
