It's asking whether szukana is in zmienna for each character in zmienna.
There are 12 characters in zmienna, so it's asking 12 times.
Because szukana is in zmienna, it adds 1 to count each time, giving a
total of 12.
If szukana wasn't in zmienna, then nothing would be added to count,
giving a total of 0.
The body of the loop should be:
for a in zmienna:
if a == szukana:
count += 1
Other notes:
0 is already an int, so int(0) is just 0!
There's no need for the 'else' part in the 'if' statement
Strings have a .count method, so you can, in fact, simplify it to just:
def gen():
return zmienna.count(szukana)
