Python_Turtle_Drunken_Pirate_Random_Math.py

##Function within a function, def stop_when_circle_xd(t,R):
##A drunk pirate has been brought in for being drunk and disorderly. The pirate
##executes a random walk of random steps, with random turn angles between
##each step, and stops first time they hit the wall, which is >= radius of
##R from its start point.
##Use user input to decide the jail cell size and draw a circle of radius R.
##Use turtle position() function, which returns the x and y coordinate
##for the current position of the turtle.
##Print out the number of steps drunken pirate takes before
##hitting jail cell wall.
