Using python I'm trying to create a code that follows the specifications below: A Picologo program consists of zero or more commands ending with the x command. Any input following an x command is ignored. The Picologo commands are processed in the order in which they appear. Picologo programs may also contain blank, zero-length lines that should be skipped and do not otherwise affect the processing of the Picologo program. A nonblank line will contain exactly one Picologo command. A picologo command may be one of the following: - b: moves the turtle backward 1 unit - d: places the turtle's pen down - f: moves the turtle forward 1 unit - l: turns the turtle to the left by 1 degree - r: turns the turtle to the right by 1 degree - u: raises the turtle's pen up - x: exits the Picologo program
