Add example for failing type conversion

[crlna16]

Added an example where the type conversion from str to int fails for illutrative purposes. It is a common error and it is good for beginners to see it explicitly.

Thank you for the PR @crlna16 ! This example is appreciated, but we have a similar exercise already in http://swcarpentry.github.io/python-novice-gapminder/03-types-conversion/index.html#strings-to-numbers where we try to convert int('3.4') - it might be good to reiterate though, thoughts from others?

Such an example makes more sense in this subsection (Must convert. <http://swcarpentry.github.io/python-novice-gapminder/03-types-conversion/index.html#-must-convert-numbers-to-strings-or-vice-versa-when-operating-on-them>..) than the old example (under Variable only change <http://swcarpentry.github.io/python-novice-gapminder/03-types-conversion/index.html#variables-only-change-value-when-something-is-assigned-to-them> ..) Would be good to clean up the sections to focus on type conversion and assignment separately which are very different topics with their own set of difficulties. Olav
