​​ For the _readline_ module, there is a typo in the second code example, starting with the documentation for Python 3.5 (I have also noticed it in the documentation for the Python 3.6 (dev) documentation). import atexitimport osimport *realine*histfile = os.path.join(os.path.expanduser("~"), ".python_history") Should be fixed to: import atexitimport osimport *readline*histfile = os.path.join(os.path.expanduser("~"), ".python_history") Referenced URL(s): - https://docs.python.org/3.5/library/readline.html - https://docs.python.org/3.6/library/readline.html -- ​​ Alec Nunn ​alec.nunn@gmail.com​ ​​
