don't understand, is to refresh the what?

Put one of the most simple example

 import time 
The import curses 
The from the curses import wrapper 

Def screen_size_changed (screen) : 
The count=0 
While True: 
Time. Sleep (1) 
If the count & gt; 10: 
Break 
Count +=1 

Num_rows, num_cols=screen. Getmaxyx () 
Print (" Rows: {}, Colums: {} ". The format (num_rows num_cols)) 

Curses. Endwin () 


If __name__=="__main__" : 
Screen=curses. Initscr () 
Wrapper (screen_size_changed)

The function of the code above is the biggest size within 10 to print the current screen (print will be a little messy, but not affect test result), you can simply try, during this time, you to change the window size, get the size of the values are the same, I just don't understand why is this
