problem with print() and threading

Question

not a big problem but i made a basic packet flooding script, but apparently print() has issues when threaded? any idea how toprevent the random blank lines? Thanks! (going to be a part of an anti-Ddos script, working my knowledge up so i can hopefully make it good enough for others to use :)

Hello @Kody. I haven't found any problem. But you must give the inputs in this format:
###

###
In different lines. Try this and tell me, please.

'#

#'
it goes more like
'#
