在python中打印和编辑多个列表

Question

Im trying to create a small text based game, and to achieve this I am created 20 lists, added 75 spaces to fill the lists, then printed each of the lists one at a time, all at the same time. I was hoping to then be able to edit the lists at certain positions so that when the lists were printed again, the console would display text where I placed it. This is what I came up with so far...

The desired effect was to have the console print this:

  ============================ 
  =                          = 
  =      TEXT ADVENTURE:     = 
  =    WAR OF ZE MONSTERS    = 
  =                          =
  ============================ 

But instead I get this:

===========================

I don't know exactly what is happening with my draw function or my write function but (to me) it would seem as if it should work.

Any help would be amazing as I am relatively new to python. Thanks in advance!

If you want to manage a text based "screen", you would be better off using the curses module. This is designed exactly for what you want, though it is somewhat complicated. Also, you could make your program about eighteen times shorter by using more functions, because you are repeating the same code many times.
