在python中从文件中随机选择单词

Question

在我的代码中，我有一个文本文件，我必须从中随机读取单词来玩hangman，但它不能正常工作，因为它会使我的游戏崩溃，因为有时它会生成一个空单词，而不是选择一个，所以当我运行它时，有时它只会说你是赢家并完成游戏。如果你能告诉我我做错了什么，那就太好了。

我的代码：

import random
import pygame
import math
pygame.init()
WIDTH , HIGHT =800,500
win=pygame.display.set_mode((WIDTH,HIGHT))
pygame.display.set_caption("hangman")
#button variables
RADIUS =20
GAP=15
letters=[]
startx=round((WIDTH-(RADIUS*2+GAP)*13)/2)
starty=400
A=97
for i in range(26):
x=startx + GAP* 2+ ((RADIUS*2+GAP) * (i % 13))
y=starty +((i // 13) * (RADIUS*2 + GAP))
letters.append([x,y,chr(A+i),True])

#Fonts
LETTER_FONT=pygame.font.SysFont('comicsans',40)
WORD_FONT=pygame.font.SysFont('comicsans',50)
TITLE_FONT=pygame.font.SysFont('comicsans',60)
#loading images
image={0:pygame.image.load(r'C:UserskimiaPycharmProjectspythonProject1imageshangman0.png'),1:pygame.image.load(r'C:UserskimiaPycharmProjectspythonProject1imageshangman1.png'),

#making a def since it is drier
def display_message(message):
pygame.time.delay(1000)
win.fill(WHITE)

win.blit(text, (WIDTH / 2 - text.get_width() / 2, HIGHT / 2 - text.get_height() / 2))
pygame.display.update()
pygame.time.delay(3000)

def hangman():

for letter in word:
if letter not in guessed:

break
if won:
display_message("YOUUU WON!")
break
if hangman_status==6:
display_message("YOU ARE A LOSER!")
break



hangman()
pygame.quit()

Answer 1

我找到了答案，我只需要用这种方式更改我的代码来消除那些空代码：

''

file=open('example.txt')
contents = file.read().splitlines()
contents = [i for i in contents if i != '' and i != ', ']
word=random.choice(contents)

''
