To illustrate, let’s execute raw_input_test_2.7.py in Python 2.7 again, but this time we’ll manually terminate the process ( Ctrl+D) once the title prompt is shown: 2.7.14 (v2.7.14:84471935ed, Sep 16 2017, 20:25:58) However, we also need to be careful that the input isn’t terminated prematurely, otherwise an EOFError will also be raised. The book you entered is 'The Stand' by Stephen King.Įverything works just fine and behaves exactly like the input() test running on Python 3.6. The resolution is to use the raw_input() function for Python 2 builds, as seen in raw_input_test_2.7.py: # raw_input_test_2.7.pyĮxecuting this in Python 2.7 produces the following output: 2.7.14 (v2.7.14:84471935ed, Sep 16 2017, 20:25:58) Consequently, The Stand isn’t valid code, so the end of file is detected and an error is thrown. Rather than converting the input value to a string, it evaluates the input as actual Python code. # If no value passed, output separator of length.Įlif len(value) ', 1, 9, 'The Stand')), False)Īs discussed earlier, the problem here is how Python 2 interprets input from the, well, input() function. :param value: Inserted text to be centered. """Print a line separator with inserted text centered in the middle.

The full exception hierarchy of this error is:īelow is the full code sample we’ll be using in this article. We’ll also look at some fully functional code examples that illustrate how the different major versions of Python handle user input, and how improper use of this functionality can sometimes produce EOFErrors, so let’s get to it! The Technical RundownĪll Python exceptions inherit from the BaseException class, or extend from an inherited class therein. Throughout this article we’ll examine the EOFError by seeing where it resides in the overall Python Exception Class Hierarchy. The EOFError is raised by Python in a handful of specific scenarios: When the input() function is interrupted in both Python 2.7 and Python 3.6+, or when input() reaches the end of a file unexpectedly in Python 2.7. Moving along through our in-depth Python Exception Handling series, today we’ll be going over the EOFError.
