Join Joe Marini for an in-depth discussion in this video Reading and writing files, part of Up and Running with Python.
Python provides built in methods for working with file types.…You can open files, write data into them, add data onto the end, read the data back…in and so on. Basically, all the things you expect to do…with file objects and that's what we're going to take a look at here in the next chapter.…So, in my example snippets I've scrolled down to the file section, and in chapter 4…lets' begin by opening up the files_start.py file, alright.…So over here in snippets, let's go ahead and copy in these lines right here, and…you don't need to do any imports here. The file type is just built into python,…so I don't need to import any classes just to be able to write files.…
So this line right here line 7, creates a variable named F.…And I'm calling the function open to open a file named textfile.txt.…So open takes 2 arguments, the file I want to open, and then a string…representing the kinds of permissions or operations I want to do on the file.…So in this case I'm passing in the letter w which means write and the plus sign…
