Hi people.
I've got a small piece of code that I don't understand. Basically, a
variable inside an if statement inside a for loop doesn't seem to be
updating. Is this a scope issue ?

Take a careful look at the variable name here: "Tempertature". Python's
dynamic nature provides a lot of wonderful benefits, but you've just hit
one of the drawbacks - you don't get any protection from typos in
variable names.

Can you provide a complete example? Your code looks correct, and should
just work.
How do you know the result contains only 't' (i.e. how do you know it
does not contain 'e', 's', 't')?
