尝试从文本文件的随机行添加文本

Question

我正在 pygame 为我姐姐在 pygame 练习游戏，我正在尝试从文本文件中随机添加一行到 window 名称：

导入pygame、随机、系统

RandomMess = open('GameText.txt')
pygame.display.set_caption('Dream Land: {}').
#The .txt file currently has 4 lines but will be a lot more in the future... 
#These are the test lines: This is in beta, hi :), hello, hi

我有所有剩余的代码，以防有人说我没有编写任何其他代码来制作 window 或任何东西。我想要它说：Dream Land: {} 然后在大括号中添加来自文件的随机行。

Answer 1

您正在寻找 readlines() 和 random.choice()。

import random,sys

RandomMess = open('GameText.txt')

# .readlines() will create a list of the lines in the file.
# So in our case ['This is in beta', 'hi :)', 'hello', 'hi']
# random.choice() then picks one item from this list.
line = random.choice(RandomMess.readlines())

# Then use .format() to add the line into the caption
pygame.display.set_caption('Dream Land: {}'.format(line))
