Hi Lu,
Python tells you:
‘<‘ not supported between instances of ‘int’ and ‘str’
This means you can’t compare two different types in Python. You can compare numbers with numbers, and you can also compare letters with letters.
I can see why you tried though since I gave an example where I did exactly that. I updated the tutorial page because I meant to give the example ‘1’ < 'a' instead of 1 < 'a'.
