Processing Strings

Question

How do you capitalize/lowercase text, and reverse the order of letters?

Answer 1

The last one is slice notation:

list[i] access to item at index i
list[start:stop] return a range copy from index start ( included ) to stop ( not included )
list[start:stop:step] return a range, using a step.

Not specifying a value set it as default 0 ( first item ) for start, and last item/index included ( last index+1 ) for stop.
Negative step would produce a reversed copy...

Answer 2

upper()
lower()
[::-1]

Answer 3

upper and lover are methods and no functions. so you should print
text.upper() and not upper(text)

Answer 4

@Alvaro I get how you use the first two, but how do you do the last one?

Answer 5

yous should do list=list[::-1]
