OK, if the python interpreter has a global hiden print out
buffer of ,say, 2to 16 K bytes, and all  string print functions
just construct the output string from the format to this string 
in an efficient low level way, then the next question 
would be that whether the uses can use functions in this 
low level buffer for other string formatting jobs.
