selecting words randomly from a file in python

Question

in my code I have text file that I have to read word randomly from it to play hangman but it does not work properly since it makes my game crash because sometimes it generates an empty word instead of selecting one so when I run it sometimes it just says you are a winner and finishes the game . It would be great if you tell me what I am doing wrong.

My code :

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:\Users\kimia\PycharmProjects\pythonProject1\images\hangman0.png'),1:pygame.image.load(r'C:\Users\kimia\PycharmProjects\pythonProject1\images\hangman1.png'),
           2:pygame.image.load(r'C:\Users\kimia\PycharmProjects\pythonProject1\images\hangman2.png'),3:pygame.image.load(r'C:\Users\kimia\PycharmProjects\pythonProject1\images\hangman3.png'),
           4:pygame.image.load(r'C:\Users\kimia\PycharmProjects\pythonProject1\images\hangman4.png'),5:pygame.image.load(r'C:\Users\kimia\PycharmProjects\pythonProject1\images\hangman5.png'),
           6:pygame.image.load(r'C:\Users\kimia\PycharmProjects\pythonProject1\images\hangman6.png')}

hangman_status=0
for i in image:
    if i ==hangman_status:
        images=image.get(i)

hangman()
pygame.quit()

Answer 1

I found the answer , I just needed to change my code in this way to get rid of those empty ones :

'''

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

'''
