HTMLTAGS - Editorial

I’ve checked all the 3 conditions still I’m getting wrong ans – Here is the code –
t = int(input())
for _ in range(t):
tags = list(input())
if tags[0] != “<” or tags[1]!="/" or tags[-1]!=’>’:
print(“Error”)
else:
for i in range(2,len(tags)-1):
if tags[i].isalnum() == False:
flag = 0
break
elif tags[i].isalpha() and tags[i].isupper():
flag = 0
break
else:
flag = 1
if flag:
print(“Success”)
else:
print(“Error”)

Assuming you mean this:

1
</A>

@ssjgz
Yes…
This will give “Error” as output because of the condition -

which is correct right…?

Your solution gives Success for that testcase.

Actually, I meant this solution
I checked on all test cases…

Oh, right:

    if flag:
NameError: name 'flag' is not defined

But, I’m not getting any error when I run it on my platform as well as on codechef platform… otherwise it would have given error msg… But i’m getting WA. Also,

this test case gives output as “Error” on codechef platform as well…

Weird - something to do with the Python version, maybe.

maybe… but I use python 3 only…

At line 8 there’s a mistake, you should iterate i to c - 2 or more specifically (i < c - 1). Then it will get accepted.

@ssjgz yeah i didn’t considered the said test case in my code.
As pointed out by @prashant_th18 i corrected that .
Thank you both of you.

hi, actually this was right… i should have defined the flag earlier before use…
But as I was running on jupyter it must have taken the previous cell’s flag and so i didn’t get the error at my side… I corrected it now, and the issue is solved… thanks a lot!!
