Using python im trying to create a code that follows these 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 sre 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 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
