Solution

If we run this script. it will ask us to enter a choice from (a/b/c/). if we enter a it will print

-----------------------------------------------------
Look how far you've come!
-----------------------------------------------------

if we enter b it will print

Oops! I must have misplaced the print_flag function! Check my source code!

if we enter c it will close the program.

We Need to make the program print the flag.

if we look at the source code we will see this:

....
    if choice == 'a':
      print_encouragement()
      
    elif choice == 'b':
      #print('\nOops! I must have misplaced the print_flag function! Check my source code!\n\n')
      print_flag()
    elif choice == 'c':
      sys.exit(0)
      
    else:
      print('\nI did not understand "' + choice + '", input only "a", "b" or "c"\n\n')

....

as we can see, if we enter b it will print the message Oops! I must have misplaced the print_flag function! Check my source code!.

We Just Need to call the function print_flag().

If we run the code with python3 serpentine.py and enter b we will get the flag.

$ python3 serpentine.py
