"From Steven D'Aprono:
* change the ask_number function
to accept a fourth argument;
* make it optional rather than
required;
* give it a sensible default
value;
* within the function, that value
must then be passed to range
"
Okay, I think I understand it better for the quesiton:
"Improve the function ask_number() so that the function can be called with a
step value. Make the default value of step 1." Here is the improved function
and the human_move function that calls it later on. The thing I am unaware of
doing is making the step value 'optional rather than required' though.
def ask_number(question, low, high, step):
"""Ask for a number within a range."""
step = 1
response = None
while response not in range(low, high, step):
response = int(input(question))
return response
def human_move(board, human):
"""Get human move."""
legal = legal_moves(board)
move = None
while move not in legal:
move = ask_number("Where will you move? (0 - 8):", 0, NUM_SQUARES, 1)
if move not in legal:
print("\nThat square is already occupied, foolish human. Choose
another.\n")
print("Fine...")
return move _______________________________________________
