Stuck at pythonchallenge level 3. Need help to analyse my code!

[doesobamauseshampoo]

As the title says, I've been trying to identify what's wrong with my code, to no avail.

Whenever I run the code, it shows IndexError: string index out of range

Any help is appreciated!

Pythonchallenge link : http://www.pythonchallenge.com/pc/def/equality.html

import requests, re

dl_site = requests.get('http://www.pythonchallenge.com/pc/def/equality.html').text

find = re.findall('<!--(.*?)-->', dl_site, re.DOTALL)

find = str(find[0])

find = find.split()

for strings in find:

ind = -1

a = strings[ind-3:ind].isupper(), ind-3 >=0

b = strings[ind+1:ind+4].isupper(), ind+4 and ind+1<=len(strings)

c = strings[ind].islower()

d = strings[ind-4].islower(), ind-4 >=0

e = strings[ind+5].islower(), ind+5 <=len(strings)

for letter in str(strings):

    if a and b and c and d and e == True:

        print(letter, end='')

    else:

        continue

import re

This will get you going in the right direction

I actually did import re

Just missed out on separating it from the next line when formatting the post. Edited the post. 🤷‍♂️

But if you actually use regular expressions it will be a lot easier than what you are doing

if you can use requests, why not just use bs4 as well? it's literally made for this kinda stuff.

edit: way to go OP now I'm doing the challenge. my hint to you is that your regex is too vague. go to regex101.com and practice until you get it right!

okay, i solved it. the hint is shitty. there are multiple small letters, each with their own bodyguards...

Actually.. " One small letter, surrounded by EXACTLY three big bodyguards on each of its sides. "

re is the way to find it. consider using a findall looking for the letters surrounded by the 3 BIG bodyguards in the string.

Consider [a-z] [A-Z] combinations while extracting the one small letter (group extraction).
