The code box below defines a variable route as a list of directions to navigate a maze. Each instruction is one of the following four basic commands: higher move one step in the positive y direction • lower. move one step in the negative y direction • left: move one step in the negative x direction • right: move one step in the positive x direction Define a function step that takes two arguments, a location (as a tuple of x and y coordinates) and an instruction (higher, lower, left, right) as a string. Given the provided location, it should return the new location (as a tuple of x and y coordinates) when following the specified instruction. If the instruction is invalid, the old location should be returned. Use the function step to determine the final position when starting from the point (0, -4) and following all instructions in the list route. Assign this final position to the variable final_point.

Question
The code box below defines a variable route as a list of directions to navigate a maze. Each instruction is one of the following four basic commands:
higher move one step in the positive y direction
• lower. move one step in the negative y direction
• left: move one step in the negative x direction
• right: move one step in the positive x direction
Define a function step that takes two arguments, a location (as a tuple of x and y coordinates) and an instruction (higher, lower, left, right) as a string. Given the
provided location, it should return the new location (as a tuple of x and y coordinates) when following the specified instruction. If the instruction is invalid, the old
location should be returned.
Use the function step to determine the final position when starting from the point (0, -4) and following all instructions in the list route. Assign this final position
to the variable final_point.
