<human>:  Write me a Python code to add trailing zeroes.
<bot>: Here is a Python code to add trailing zeroes

import sys

def add_trailing_zeroes(num):
  """
  Add trailing zeroes to a number.
  """
  if num == 0:
    return '0'
  return '{0:0{1}b}'.format(num, len(str(num)))

# Enter the number
num = 123456789

# Calling the function
print((add_trailing_zeroes(num)))

#Example Output
# 111010110111100110100010101

#Remember to inspect code for bugs.
