问题遇到的现象和发生背景
pygame模块，在游戏循环中调用前面循环中的file_name变量，但是%s后被认为file_name是字符串
问题相关代码，请勿粘贴截图
#导入pygame,os,sys,random模块

pygame.mixer.music.play(loops=1)
elif exec("%s.get_rect().collidepoint(x1,y1)" % (file_name)):
pygame.quit()
sys.exit()
运行结果及报错内容
我的解答思路和尝试过的方法
file_name = ''设置全局变量file_name为空字符串
在def jiazaishengyin():中global file_name，但是调用file_name全局变量是还是空字符串
我想要达到的结果
在elif exec("%s.get_rect().collidepoint(x1,y1)" % (file_name)):中调用file_name的值
