Hello again Everyone,
I spent a small amount of time recently writing a program that "blinks"
text. I did it by first having a user input a string,
sys.stdout.write-ing the string, then backing up judging by the number of
characters the string has, re-stdout's over it with blank spaces (judged
again by it's character count), and then backs up again in a never ending
while loop. It keeps each blink .5 seconds spaced as well, and all in the
same position.
Here is the code.
[start code]
#blinky.py
#Make a blinking user inputed (strings) character by using self made "blinky"
#function.
strings = raw_input("Please enter something to blink: ")
#blinky(string_argument, time_pause)
def blinky(strings1, pause):
import string,time,sys
string_length = len(strings1)
replacement = string.replace(strings1,strings1," ")
float(pause)
while 1:
sys.stdout.write(strings1)
sys.stdout.flush()
time.sleep(pause)
sys.stdout.write("\b"*string_length)
sys.stdout.write(" "*string_length)
sys.stdout.flush()
time.sleep(pause)
sys.stdout.write("\b"*string_length)
blinky(strings, .5)
[end code]
My question is that I was recently informed by someone that I could help
free up some memory usage by alleviating the sys.stdout.flush's in the
code, but I need those in order to keep the "blinking" text in place.
Is there any way I can actually free up memory usage in the terms of the
sys.stdout.flush that any of you can notice? I'm simply curious now after
being informed.
Thanks again,
~Ryan
