Intent is to print "Jack, Kack, ...." with "O" and "Q" delivering a longer suffix. Instead, I get
the printout shown with duplicates and a second deviation with "O" and "Q" as shown.
Why?
That's what you've told the code to do :)
prefixes = 'JKLMNOPQ' ###FAILS WITH REPEATS
### OH NO IT DOESN'T - nothing personal but it's pantomine season in the
UK :)
suffix = 'ack'
suffixb= 'uack'
for letter in prefixes:
if letter == "O":
print letter + suffixb
if letter == "Q":
print letter + suffixb
else:
print letter + suffix
You test for "O", but then follow with a test for "Q" and an else
clause. You could write :-
elif letter == "Q"
but the cleanest way of doing this is:-
for letter in prefixes:
if letter in ("O", "Q"):
print letter + suffixb
else:
print letter + suffix
