Answer 1

At First :
after a
'class String:'
Everything in the class has to be indented. So shift every line 2 Times to the right.
And you have also to intent after a "for" and after "if"

Answer 2

In line 21 and 25 the
'l' and 'L'
has to be changed to
'u' and 'U'

Answer 3

Personally, I would prefer to take out all input and output Funktion from the class.
And maybe a separat return for each Methode. In the main program it looks like this.

instr = Input()
s = String()
s.setString(instr)
upper = s.count_upper()
lower = s.count_lower()
.
.
print ('upper =', upper)

and so on

Answer 4

This one is NOT ready.
But you can see how it works. And have a look at the Intention 😉
