our
getSecretNum()
function (passing it
NUMDIGITS
to tell how many digits we
want the secret number to have) and assign it to
secretNum
. Remember that
secretNum
is a string, not an integer.
We tell the player how many digits is in our secret number by using string interpolation
instead of string concatenation. We set a variable
numGuesses
to
1
, to denote that this is
the first guess. Then we enter a new
while
loop which will keep looping as long as
numGuesses
is less than or equal to
MAXGUESS
.
Getting the Player's Guess
Notice that this second
while
loop on line 60 is inside another
while
loop that started
on line 55. Whenever we have these loops-inside-loops, we call them
nested loops
. You
should know that any
break
or
continue
statements will only
break
or
continue
out of the innermost loop, and not any of the outer loops.
61. guess = ''
62. while len(guess) != NUMDIGITS or not isOnlyDigits
(guess):
63. print('Guess #%s: ' % (numGuesses))
64. guess = input()
The
guess
variable will hold the player's guess. We will keep looping and asking the
player for a guess until the player enters a guess that has the same number of digits as the
secret number and is made up only of digits. This is what the
while
loop that starts on line
62 is for. We set guess as the blank string on line 61 so that the
while
loop's condition is
False
the first time, ensuring that we enter the loop at least once.
Getting the Clues for the Player's Guess
66. clue = getClues(guess, secretNum)
67. print(clue)
68. numGuesses += 1
After execution gets past the
while
loop on line 62, we know that
guess
contains a
valid guess. We pass this and the secret number in
secretNum
to our
getClues()
function. It returns a string that contains our clues, which we will display to the player. We
then increment
numGuesses
by 1 using the augmented assignment operator for addition.
Checking if the Player Won or Lost
70. if guess == secretNum:
71. break
72. if numGuesses > MAXGUESS:
