Exactly in what way are you trying to hoist it outside of the loop? The way
UpperCaseSentence is defined right now, it depends on myString, which
exists only inside the loop. You can't move that out of the loop since
myString won't exist there.

A few other comments:

- tempString[0:1] may be written as tempString[:1]. Similarly,
tempString[1:len(tempString)] may be written as tempString[1:]. In simple
terms, you can leave out part of the slice and it will default to the end
or beginning.
-  You might want to have a look at str.capitalize(). It does exactly what
you need.
