Objectives
Level Goal The password for the next level is stored in the file data.txt and is the only line of text that occurs only once

bandit8@bandit:~$ cat data.txt | sort |uniq -uUsvVyFSfZZWbi6wgC7dAFyFuR6jQQUhR

that was pretty easy

now let's python that thing..

​with open("data.txt") as f: orig = list(f) filtered = [x for x in orig if orig.count(x)==1] print("".join(filtered))


>>> with open("data.txt") as f:...  orig = list(f)...  filtered = [x for x in orig if orig.count(x)==1]...  print("".join(filtered))...UsvVyFSfZZWbi6wgC7dAFyFuR6jQQUhR
