OTOH, learning that translating a user-entered string to a floating point number is not as simple as it sounds is a great lesson. Please don't teach beginners that handling user input (let alone floating point arithmetic) is easy and/or foolproof. Start with letting the program fail when the input is invalid, teach them to isolate input validation into its own function(s), and introduce try/except as one method of control flow in a validation function. _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/GKMQV75D5PXLTC6SE2V7YFNHLKKPVN52/ Code of Conduct: http://python.org/psf/codeofconduct/
