这是我在游戏Hangman
的书中找到的代码:
HANGMAN=("""

MAX_WRONG = len(HANGMAN) - 1
WORDS = ("OVERUSED", "CLAM", "GUAM", "TAFFETA", "PYTHON", "HARDWICKE", "BRADLEY", "SHEFFIELD")
# initialize variables
word = random.choice(WORDS) # the word to be guessed
so_far = "-" * len(word) # one dash for each letter in word to be guessed
wrong = 0 # number of wrong guesses player has made
used = [] # letters already guessed
print("Welcome to Hangman. Good luck!")
while wrong < MAX_WRONG and so_far != word:
print(HANGMAN[wrong])
print("\nYou've used the following letters:\n", used)
print("\nSo far, the word is:\n", so_far)
print("\nOnly use one letter values, more than one letter at a time does not work at this time")
guess = input("\nEnter your guess: ")
guess = guess.upper()
while guess in used:
print("You've already guessed the letter", guess)
guess = input("Enter your guess: ")
guess = guess.upper()
used.append(guess)
if guess in word:
print("\nYes!", guess, "is in the word!")
# create a new so_far to include guess
new = ""
for i in range(len(word)):
if guess == word[i]:
new += guess
else:
new += so_far[i]
so_far = new
else:
print("\nSorry,", guess, "isn't in the word.")
wrong += 1
if wrong == MAX_WRONG:
print(HANGMAN[wrong])
print("\nYou've been hanged!")
else:
print("\nYou guessed it!")
print("\nThe word was", word)
input("\n\nPress the enter key to exit.")
我不明白这部分代码:
if guess in word:
print("\nYes!", guess, "is in the word!")
# create a new so_far to include guess
new = ""
for i in range(len(word)):
if guess == word[i]:
new += guess
else:
new += so_far[i]
so_far = new
else:
print("\nSorry,", guess, "isn't in the word.")
wrong += 1
这部分代码必须制作一个新的变量sofar,它会在右侧位置显示一个带有猜测字母的目标词
# create a new so_far to include guess
new = ""
for i in range(len(word)):
if guess == word[i]:
new += guess
else:
new += so_far[i]
so_far = new
我完全不理解这最后一部分 求救!
答案 0 :(得分:0)
new = "" #creates an empty string named new
for i in range(len(word)): #loop x times,x is word size,e.g. len("PYTHON") is 6
if guess == word[i]:
new += guess #adds the guess character to new string
else:
new += so_far[i] #adds the existing character from so_far string(on first loop is '_')
so_far = new
实施例: word = PYTHON,guess =&#39; T&#39; ,so_far是_ _ _ _ _ _
在for循环后
so_far是_ _ T _ _ _
