So, after searching the net for a good way to clear the line (without doing stupid shit like os.system('clear')) i came across these 2 hexcodes ^^

clearLine = "\x1B\x5B\x32\x4B\x1B\x5B\x47"
clearAll =  "\x1B\x5B\x48\x1B\x5B\x32\x4A"

Their variable names say it all, one will clear the line where your cursor is, and the other will clear the entire screen.

Heres a fun little "wait" function im using in one of my scripts...

import sys,time,random
def funPrint(x,f,t=0.1):
	left = x
	cl = "\x1B\x5B\x32\x4B\x1B\x5B\x47"
	while left > 0:
		if left-t < 0: t=left
		sys.stdout.write(cl+"Wait [ %.1f ] seconds"%left)
		sys.stdout.flush()
		time.sleep(t)
		left -= t
	sys.stdout.write(cl+f)
	sys.stdout.flush()

for x in range(5):
	funPrint(random.uniform(1.3, 3.9), "Checking something...")
	time.sleep(1)

print
print "Were done waiting "

Enjoy

Wouldn't it be easier to use:

import sys



def clearLine(string='',end=None):

	print("\x1B\x5B\x32\x4B\x1B\x5B\x47"+string,end=end)



def clear():

	print("\x1B\x5B\x48\x1B\x5B\x32\x4A",end='')

Well yeah The point wasn't to show the most effective way of using it >> In my script i have a whole print class which has those 2 methods devoted to clear line and clear screen ^^

I'll definitely be using these code snippets. I'm just starting to learn, and before now the only way I knew how to clear the screen was the lame 'Import OS' example you gave.

How did you figure out/stumble upon this hex code? How would one go about deciphering commands to hex code like this?

Google and this xD
