Python Tanks - Use print to spy more info!

We have used 'look_ahead()' function to check there is no wall ahead.
But in this exercise there is not the wall but the border of the field!
What does this function return on the border? Let us use 'print()' to investigate!

Prev
#let us drive to nearest border #and print what 'look_ahead()' returns! forward() left() forward() print(look_ahead()) #when we have found the necessary info #let us remove all the spying code above #and fix the code below to reach the border #then turn right and reach the star while look_ahead() != 'wall': forward() print('Turning at the border!') right() while look_ahead() != 'wall': forward() print('Corner was reached!') pick() #hint replace the 'wall' with the word we have spied!
