[Tutor] a question about exceptions

[tpc at csua.berkeley.edu]

hi Tony,

I don't know if you know this, but in the C programming language there is
an atoi() function that converts an array to int.  During runtime you will
get an error if what is passed is not an array or, in the case of an
array of chars, if not every char is a digit.  I don't know enough of
Python to say anymore than what I have learned in my community college C
class.

I hope this helps you.
