我正在继续使用Hangman项目，我遇到了for循环问题并在其中执行了一个函数。例如，如果您按下名为“加拿大”的级别，并按“B”，因为加拿大没有B，它应该绘制Hangman的第一行。这就是我到目前为止所做的：
def hangman1():
pygame.draw.line(screen, black, (775, 250), (775, 50), (4))
def hangman2():
pygame.draw.line(screen, black, (750, 250), (800, 250), (4))
def hangman3():
pygame.draw.line(screen, black, (775, 50), (925, 50), (4))
def hangman4():
pygame.draw.line(screen, black, (925, 50), (925, 175), (4))
def hangman5():
pygame.draw.circle(screen, black, (925, 100), 30, (0))
def hangman6():
pygame.draw.line(screen, black, (925, 125), (925, 200), (4))
def hangman7():
pygame.draw.line(screen, black, (885, 160), (965, 160), (4))
def hangman8():
pygame.draw.line(screen, black, (925, 200), (900, 225), (4))
def hangman9():
pygame.draw.line(screen, black, (925, 200), (950, 225), (4))
再多一点代码......
letters = list('abcdefghijklmnopqrstuvwxyz')
a = font2.render(str(letters[0]), True, (black))
b = font2.render(str(letters[1]), True, (black))
c = font2.render(str(letters[2]), True, (black))
d = font2.render(str(letters[3]), True, (black))
e = font2.render(str(letters[4]), True, (black))
f = font2.render(str(letters[5]), True, (black))
g = font2.render(str(letters[6]), True, (black))
h = font2.render(str(letters[7]), True, (black))
i = font2.render(str(letters[8]), True, (black))
j = font2.render(str(letters[9]), True, (black))
k = font2.render(str(letters[10]), True, (black))
l = font2.render(str(letters[11]), True, (black))
m = font2.render(str(letters[12]), True, (black))
n = font2.render(str(letters[13]), True, (black))
o = font2.render(str(letters[14]), True, (black))
p = font2.render(str(letters[15]), True, (black))
q = font2.render(str(letters[16]), True, (black))
r = font2.render(str(letters[17]), True, (black))
s = font2.render(str(letters[18]), True, (black))
t = font2.render(str(letters[19]), True, (black))
u = font2.render(str(letters[20]), True, (black))
v = font2.render(str(letters[21]), True, (black))
w = font2.render(str(letters[22]), True, (black))
x = font2.render(str(letters[23]), True, (black))
y = font2.render(str(letters[24]), True, (black))
z = font2.render(str(letters[25]), True, (black))
则...
hangman = [hangman1, hangman2, hangman3, hangman4, hangman5, hangman6, hangman7, hangman8, hangman9]
for linebyline in hangman:
...后来
elif b1.collidepoint(pygame.mouse.get_pos()):
letter = letters[1]
check = country.count(letter)
if check >= 1:
if letter == letters[0]:
aPosition = 325, 235
a3 = screen.blit((a), (375, 235))
a4 = screen.blit((a), (425, 235))
a1.x, a1.y = -500, -500
elif letter == letters[2]:
cPosition = 300, 235
c1.x, c1.y = -500, -500
elif letter == letters[13]:
nPosition = 450, 235
n1.x, n1.y = -500, -500
elif letter == letters[3]:
dPosition = 600, 235
d1.x, d1.y = -500, -500
else:
b2 = font.render(str(letters[1]), True, (red))
screen.blit(b2, (485, 325))
linebyline()
time.sleep(0.5)
bPosition = -500, -500
b1.x, b1.y = -500, -500
当我按下B时，它变为红色，并在0.5秒内消失，但它不会画线。有什么帮助吗？
编辑：我使用另一个模块进行了一些测试，并且打印普通文本时功能完美正常。但是当我用绘图（Pygame）再次测试它时，它可以工作，但当结合其他东西（如time.sleep()）时，它会显示一个白色的屏幕。当与print组合时，绘图的东西不起作用，但打印确实有效。此外，如果我添加time.sleep(1)，它将有一个黑色屏幕正好9秒，没有做任何其他事情。这是我的测试代码：
import pygame, sys, random, time
from pygame.locals import *
pygame.init()
screen = pygame.display.set_mode((1000, 700))
pygame.display.set_caption("Hangman: Countries")
black = 0, 0, 0
def hangman1():
pygame.draw.line(screen, black, (775, 250), (775, 50), (4))
print 'test'
def hangman2():
pygame.draw.line(screen, black, (750, 250), (800, 250), (4))
print 'test somethin'
def hangman3():
pygame.draw.line(screen, black, (775, 50), (925, 50), (4))
print 'test something else'
def hangman4():
pygame.draw.line(screen, black, (925, 50), (925, 175), (4))
print 'eggs'
def hangman5():
pygame.draw.circle(screen, black, (925, 100), 30, (0))
print 'hangman'
def hangman6():
pygame.draw.line(screen, black, (925, 125), (925, 200), (4))
print 'facebook'
def hangman7():
pygame.draw.line(screen, black, (885, 160), (965, 160), (4))
print 'internet'
def hangman8():
pygame.draw.line(screen, black, (925, 200), (900, 225), (4))
print 'more tests'
def hangman9():
pygame.draw.line(screen, black, (925, 200), (950, 225), (4))
print 'cheese'
while True:
for event in pygame.event.get():
if event.type == QUIT:
pygame.quit()
sys.exit()
screen.fill((255, 255, 255))
list1 = [hangman1(), hangman2(), hangman3(), hangman4(), hangman5(), hangman6(), hangman7(), hangman8(), hangman9()]
for greet in list1:
greet
time.sleep(1)
pygame.display.flip()
它在shell中同时打印一堆单词，然后在9秒后屏幕变为完全绘制的刽子手，同一组单词重新开启。任何想法，你们中有谁在Pygame有经验吗？
答案 0 :(得分：1)
我刚刚制作了一个正常运行的刽子手程序。也许看这个逻辑会有所帮助：
忽略这一点：
#!/usr/bin/python
import string
alphabet = string.ascii_lowercase
# represents drawing routines
def hangman1():
print(1)
def hangman2():
print(2)
def hangman3():
print(3)
# ignore this, never do this:
def myprint(x): #python2 hack, unnecessary in python3
print(x)
for i in range(1,10):
globals()['hangman{}'.format(i)] = lambda i=i: myprint('bodypart#{}'.format(i))
# ignore this
class EnumItem(object):
def __init__(self, namespace, namespace_name, value):
self.namespace = namespace
self.namespace_name = namespace_name
self.value = value
def __repr__(self):
return '{}.{}'.format(self.namespace_name, self.value)
class Enumeration(object):
def __init__(self, prefix, names):
prefix = prefix.upper().replace(' ','_')
globals()[prefix] = self #don't do this with locals()
self.items = names
for i,name in enumerate(names.strip().splitlines()):
name = name.strip().upper().replace(' ','_')
value = EnumItem(self, prefix, name)
setattr(self, name, value)
#globals()[name] = value #optional, also don't do this with locals()
一些枚举：
Enumeration('GAME_STATE', '''
active
lost
won
''')
Enumeration('GUESS', '''
invalid not a letter
invalid already guessed
correct
correct win
incorrect
incorrect loss
''')
游戏逻辑 - 如果您在思考刽子手的规则时遇到困难，请查看此部分（我省略了一些事情，使其完全正确地使用空格运行，以便更容易理解） ：

self.num_incorrect_guesses = 0
self.game_state = GAME_STATE.ACTIVE
def guess(self, letter):
"""

# else guess is legitimate
self.guessed.add(letter)
if letter in self.phrase: # if guess was correct
# update internal state
self.revealed = ''.join((c if c in self.guessed else (' ' if c==' ' else '?')) for c in self.phrase)
# check for win
print(set(self.guessed), set(self.phrase))
if self.guessed>=set(self.phrase): # non-strict superset, see set.__ge__ etc.
self.game_state = GAME_STATE.WON
self.redraw
return GUESS.CORRECT_WIN
else:
return GUESS.CORRECT

交互式循环：
