Instruction
Great! Let's start with a very basic example in which we'll open a file and print its contents:
file = open('employees.txt')
print(file.read())
file.close()
And that's it! Python comes with some built-in file functions that are easy to use.
- The
open()function opens a file whose filename is given as the argument. To clarify,open()doesn't actually open any files; rather, it returns a so-called file object that represents the corresponding file on your computer. You must assign that object to a variable if you want to use it. In our case, that variable is simply calledfile. - To get the entire contents of the file, use
file.read(). As you can see, you can pass that result toprint()to show the file's contents in the console. file.close()closes the file so you can no longer read it (unless you open it again). Remember to put this statement in your code when you're done with a file.
Exercise
Open a file named daily_sales.txt and print its contents. Close the file afterwards.
Stuck? Here's a hint!
The argument of open() should be 'daily_sales.txt'.
