   Approach

   Method 1

   Read and follow the hints

   Method 2

   If you open runme.py you’ll see the code: ```python #!/usr/bin/python3 ################################################################################

   Python script which just prints the flag

   ################################################################################

flag =’picoCTF{run_s4n1ty_run}’ print(flag)

The first few lines are [comments](https://en.wikipedia.org/wiki/Comment_(computer_programming)) meaning the computer doesn't look at it. The lines the computer will look at are here:
```python
flag ='picoCTF{run_s4n1ty_run}'
print(flag)

flag ='picoCTF{run_s4n1ty_run}' will define a variable flag with the value “picoCTF{run_s4n1ty_run}”. The next line print(flag) will print the value contained in flag, so “picoCTF{run_s4n1ty_run}”.

Flag

picoCTF{run_s4n1ty_run}
