Get the Player's Guess
The
getGuess()
function we create next will be called whenever we want to let the
player type in a letter to guess. The function returns the letter the player guessed as a string.
Further,
getGuess()
will make sure that the player types a valid letter before returning
from the function.
85. def getGuess(alreadyGuessed):
86. # Returns the letter the player entered. This
function makes sure the player entered a single letter,
and not something else.
The
getGuess()
function has a string parameter called
alreadyGuessed
which
contains the letters the player has already guessed, and will ask the player to guess a single
letter. This single letter will be the return value for this function.
87. while True:
88. print('Guess a letter.')
89. guess = input()
90. guess = guess.lower()
We will use a
while
loop because we want to keep asking the player for a letter until
they enter text that is a single letter they have not guessed previously. Notice that the
condition for the
while
loop is simply the Boolean value
True
. That means the only way
execution will ever leave this loop is by executing a
break
statement (which leaves the
loop) or a
return
statement (which leaves the entire function). Such a loop is called an
infinite loop
, because it will loop forever (unless it reaches a
break
statement).
The code inside the loop asks the player to enter a letter, which is stored in the variable
guess
. If the player entered a capitalized letter, it will be converted to lowercase on line
90.
elif
("Else If") Statements
Take a look at the following code:
if catName == 'Fuzzball':
print('Your cat is fuzzy.')
else:
print('Your cat is not very fuzzy at all.')
We've seen code like this before and it's rather simple. If the
catName
variable is equal
to the string
'Fuzzball'
, then the
if
statement's condition is
True
and we tell the user
