你的代码中有几个问题。
在这里，您有一个可以分析的功能版本(让我们将'hello'设置为目标词)：
word = 'hello'
so_far = "-" * len(word) # Create variable so_far to contain the current guess
while word != so_far: # if still not complete
print(so_far)
guess = input('>> ') # get a char guess
if guess in word:
print("\nYes!", guess, "is in the word!")
new = ""
for i in range(len(word)):
if guess == word[i]:
new += guess # fill the position with new value
else:
new += so_far[i] # same value as before
so_far = new
else:
print("try_again")
print('finish')我试着用py2k ide为py3k写它，小心错误。
