Instruction
Okay! Now that we have a function which returns the game board and we have a proper robot representation, we need a function which will print (visualize) the board after each game round. We want the function to print to the console output. It should look something like this:
======================== - - - - - A>- - - - - - - - B<-
First, we introduce a horizontal line that visually separates the different rounds. (Each round will print out its own board.) After the line, we print our 4 x 4 board. Note that each field is visualized with two characters: empty fields have hyphens followed by spaces, and the occupied fields contain robot names and the direction that robot faces.
Exercise
Create a function named print_board(board, robot_a, robot_b). The function accepts a board in the format we specified earlier and two robot dictionaries.
Start by printing a separating line (there are 24 equality signs in the line):
========================
Next, for each cell in the board, print two characters as outlined below.
- If the cell is an empty field (
'-'), print a hyphen followed by a space ('- '). - For a cell with either
'A'or'B', print the letter followed by that robot's direction.
Invoke the print_board() function with the initial board and robot configuration.
Stuck? Here's a hint!
You will need a nested for loop:
for row in board:
line = ''
for cell in row:
if cell == ...
To get a robot's direction, use the input argument robot_a or robot_b. It is a dictionary which contains a field named direction:
robot_a['direction']
