Let’s say we want to write “Hello, New Stack” to a file called text.txt. We’re going to focus on the write and append modes. If the file doesn’t exist, it is created. Append Only (a) – opens a file for writing.Write and Read (w+) – opens a file for both writing and reading.Write only (w) – opens a file for writing.There are three different modes for this: To do this, we have to open a file (from within Python) in what’s called access mode. The first thing you need to learn is how to write data to a file. We’re going to take this one step at a time. If, however, you’re working on a different OS, you might have to adjust here or there if things don’t work out as expected (they should though). However, it will work on any operating system that supports Python. Once again, I’ll be demonstrating this process on Linux. So this is similar to Algebra in high school… you will use it later in life. Also, it’s an important trick for when you’re doing more advanced Python work. This can be handy if you want to keep track of a list of things but don’t always want to open the file to do so.

This time around we’re going to create a program that uses much of what we’ve already learned adds some new bits and put it all together to create a program that can take input from a user and save it to a file. With that knowledge, we’ve created a couple of interesting little programs that illustrate how these features work in Python, but the applications themselves don’t do much outside of proving to your friends and family that you can learn a programming language.

We’ve learned what makes the language special, learned about the Python console and used variables, and learned how to accept input from users. So far in this introductory series to the Python programming language, we’ve learned some pretty cool basic Python tricks.
