Python scripts are invoked kind of like programs in the Terminal... Can you run this Python script using this password to get the flag?

Write up:

Running the script by itself we get the following usage:

python3.8 ende.py  

Usage: ende.py (-e/-d) [file]

So then I tried running it with the file:

python3.8 ende.py -d flag.txt.en                                                           

Please enter the password:

I didn't feel like manually typing the password so I used cat and a pipe:

cat pw.txt | python3.8 ende.py -d flag.txt.en
