File I/O in Python: the readline function (reading text files one line at a time)
You usually want to read a text file one line at a time, using the "readline" function in conjunction with a loop. In this example, we use a while loop to read a simple file, and show what happens when you try to read past the end of the file. Check out the notebooks linked below for more information on file handling in Python.
