Python Programming with Raspberry Pi

Reading from a file

Let's create a simple text file, read_file.txt with the following text: I am learning Python Programming using the Raspberry Pi Zero and save it to the code samples directory (or any location of your choice).

To read from a file, we need to make use of the Python's in-built function: open to open the file. Let's take a quick look at a code snippet that demonstrates opening a text file to read its content and print it to the screen:

Let's discuss this code snippet in detail:
