print is slow

Pythonista using print function is very slow.
can using other method to improve speed?
-
Where possible, try to call
print()
as few times as possible by bundling up a bunch of lines of text into just one call toprint()
.Like:
my_text = '''Triple quoted strings allow you to create strings that are multiple lines long.''' print(my_text) # is faster than for line in my_text.splitlines(): print(line) # or use str.join() import string print('\n'.join([c for c in string.lowercase])) # is faster than for c in string.lowercase: print(c)

thanks @ccc
s=''
for i in range(100):
s += 'test afsdafdsaf\n'
print sit's fast,but sometime I need print split. etc: output process info.
can speed up every time print output ?

Is the text that you a printing out for your end user or is it just for you own debugging purposes? If the latter, consider using
logging
instead of printing.It is also possible to redirect stdout to a file instead of the console which will be much faster but I find that complex/counterintuitive.
You could also create a ui.TextView and write your text there:
text_view.text += 'new message'
