Challenge: Useless Python----------------------------------------Category: Programming----------------------------------------50 points ----------------------------------------Description:```Boredom took over, so I wrote this python file! I didn't want anyone to see it though because it doesn't actually run, so I used the coolest base-16 encoding to keep it secret. python ```useless.py
The python scrypt is encoded with base16, decoder gives me this:
exec(chr(101)+chr(120)+chr(101)+.....)
Code:```with open ('base16.txt', 'r') as f:    num = ''    for char in f.read():        m = char        if m != '+' and m != '(' and m != ')' and m != 'c' and m != 'h' and m != 'r':            num += m        else:            if num != '' and num != '+' and num != '(' and num != ')' and num != 'c' and num != 'h' and num != 'r':                sim = chr(int(num))                with open ('text.txt', 'a') as out:                out.write(sim)            num = ''```After a few iterations:```flag = 'easyctf{python_3x3c_exec_3xec_ex3c}'priint flag```
flag = 'easyctf{python_3x3c_exec_3xec_ex3c}'
