It took me a while to get this one correct, and it's because I found part of the descritpion to be ambiguous/unclear - so I'm posting this clarification which hopefully will help anyone else who has the same misunderstanding.

"if a student has got satisfactory marks, the scholarship is not given, "

I read this to mean "got ONLY satisfactory marks" but my solutions were rejected.
Once I modified my solution to treat it as "got ANY satisfactory marks", the solution was accepted.

a = int(input())
f = []
for i in range(a):
    s = int(input())
    f.append(s)
if f.count(3) >=1:
    print('None')
else:
    if f.count(5) == len(f):
        print('Named')
    elif sum(f) / len(f) >=4.5:
        print('High')
    else:
        print('Common')

if u wanna break your programm type sys.exit() (don't forget to type import sys in the beginning of the programm)
_____________________
если вы хотите полностью прервать вашу программу, то импортируйте библиотеку sys и пропишите sys.exit()

dont use ',' use '.' at 4.5

Please read "if a student has got satisfactory marks, the scholarship is not given" this statement again and again which means if in any of the subject a student gets 3.0 he will not get any scholarship.

--------------------------------------------------
Пожалуйста, прочитайте «если студент получил удовлетворительные оценки, стипендия не предоставляется», это утверждение снова и снова означает, что если по какому-либо предмету студент получает 3,0 балла, он не получит стипендию.

Can someone give 5^th test?
I got WA5;

var n,i,o,c,p,x:integer;
     s:real;
begin
s:=0;p:=0;
readln(n);
for i:=1 to n do begin
readln(o);
s:=s+o;
end;
s:=s/n;
if o = 3 then begin
inc(c);
writeln('None');
end;
if s=5 then if (c<>1) then begin
     inc(p);
     writeln('Named');end;
if s>=4.5 then if (c<>1)and (p<>1) then begin
inc(x);
writeln('High'); end;
if (c<>1) and (p<>1) and (x<>1) then
writeln('Common');
end.
