	# color = "#4A7023"
	characters = "10"
	# characters = string.letters
	# How long?
	cols = 75
	# For loop
	while True:

		for x in range(0, cols):

			# print colored(random.choice(characters))
			randomchoice = random.choice(characters)
			# add to final_string
			final_string += randomchoice
		# print final_string (full string with {cols} length of characters
		print (final_string)
	# print new line
	print("\n")
