Hello @sirius911,
You are misunderstanding the notion of characters. The exercise is correct.

Have a nice day

Hello,
Ok, so when the example writes:

$> python3 count.py 'Hello World!'
The text contains 8 characters:
- 2 upper letter(s)
- 8 lower letter(s)
- 1 punctuation mark(s)
- 1 space(s)

8 characters means 8 lower letters ?(I am talking about the first line displayed and not the detail that follows)
because for me Hello World! contains 8 lower letters, 2 upper letters,1 punctuation and 1 space, which makes a total of 12 letters.
It's strange to display this line first, especially since the following seems to be the detail of this total number of characters. We tend to write the total number of characters first.
Thanks.
Have a good day
Thanks.

Hello,
i have the same issue in this exercise, do you guys have any update?
thanks in advance!

The count does not refer to lowercase or uppercase.
In "Hello World!" one can observe that you have the fonts 'H', 'e', 'l', 'o', 'W', 'r' 'd' and '!' which make 8 unique font sign.
I will consider adding another examples then

Hello, thank you for answering, but i'm still confused, because based on the example you gave, this one (from subject) is wrong:

>>> text_analyzer("Python 2.0, released 2000, introduced
features like List comprehensions and a garbage collection
system capable of collecting reference cycles.")
The text contains 143 character(s):
- 2 upper letter(s)
- 113 lower letter(s)
- 4 punctuation mark(s)
- 18 space(s)

can you please investigate this case?
thanks again

Oh ! I remember, it is referring to printable characters
