fixme1.py

Lets download that script:

curl -s https://artifacts.picoctf.net/c/25/fixme1.py -o fixme1.py

If we read it and run it with python3:

cat fixme1.py

python3 fixme1.py

There is an indentation in the last line, we can remove it:

Open it with vim:

vim

:wq

cat fixme1.py

If we run it now:

python3 fixme1.py

Here is the flag.
