Solve the following python programming problem given the following code:
# Inheriting from the Thread class

from threading import *

class lift_off(Thread):
    def __init__(self, number):
        Thread.__init__(self)
        self.number = number
    def run(self):
        for i in range(3,0, -1):
            print("#"+ str(i) + "("+ str(self.number) + ") ")

for x in range(7):
    lift_off(5).start()
Given the above code, generate some markdown instructions for it.
