For this challenge, we need to reverse a briefly obfuscated python script to find an input value that will validate some conditions to get the flag.
from binascii import unhexlify as sOup
from operator import attrgetter as souP
ME_FLAGE = 'censored'
SoUp = input
soUP = hex
sOUp = print
sOuP = ord
SOuP = open
soup = 0
while sOUP != 0:
soup = (soup * 10) + (sOUP % 10)
sOUP //= 10
soup = 0
for soUp in sOUP:
soup *= 10
soup += sOuP(soUp) - sOuP('0')
Soup = SoUp()[:7]
if not souP('isdigit')(Soup)():
sOUp("that's not a number lol")
soup = SoUP(SOup(Soup))
SouP = souP('zfill')(soUP(soup)[2:])(8)[-8:]
if sOup(SouP) == souP('encode')('s0up')():
sOUp("oh yay it's a flag!", ME_FLAGE)
sOUp('oh noes rip u')
