def concat_string_and_datetime(string, datetime):
  """Concatenate a string and a datetime object."""
  return string + datetime.strftime("%Y-%m-%d %H:%M:%S")

# Enter the string
string = "lilly"

# Enter the datetime
datetime = datetime.datetime(2019, 1, 1)

# Calling the function
print((concat_string_and_datetime(string, datetime)))
