# Constructor with three parameters:
#  hours, minutes, seconds with default values 0.
# Three instance variables: hours, minutes, seconds.
# A method called str_update(). 
# It takes as an argument a string of the form hh:mm:ss and updates
# the three instances variables.
# A __str__() method for responding to the print() method. 
# It should write out: "{} hours, {} minutes and {} seconds"
# A method called add_clocks().
#  It takes another clock object as a parameter,
# adds the two clocks and returns a new clock instance. 
# In this method, you need to add the respective values of the two clocks together
# and remember the resulting hours, minutes and seconds. 
# Remember that the sum of seconds cannot exceed 60,
#  in which case there is a carry over to the minutes values.
# Same for minutes, it cannot exceed 60 and carries over to hours.
#  For hours, the summed values cannot exceed
# 23. If hours is exceeded, we ignore it. 
#  Use the divmod() built-in Python function in your implementation.
