To whom it may concern,
I need help on this assignment:
Create a new class, SMS_store. The class will instantiate SMS_store objects,
similar to an inbox or outbox on a cellphone:
my_inbox = SMS_store()
This store can hold multiple SMS messages (i.e. its internal state will just be
a list of messages). Each message will be represented as a tuple:
(has_been_viewed, from_number, time_arrived, text_of_SMS)
The inbox object should provide these methods:
my_inbox.add_new_arrival(from_number, time_arrived, text_of_SMS)
# Makes new SMS tuple, inserts it after other messages
# in the store. When creating this message, its
# has_been_viewed status is set False.
my_inbox.message_count()
# Returns the number of sms messages in my_inbox
my_inbox.get_unread_indexes()
# Returns list of indexes of all not-yet-viewed SMS messages
my_inbox.get_message(i)
# Return (from_number, time_arrived, text_of_sms) for message[i]
# Also change its state to "has been viewed".
# If there is no message at position i, return None
my_inbox.delete(i) # Delete the message at index i
my_inbox.clear() # Delete all messages from inbox
Write the class, create a message store object, write tests for these methods,
and implement the methods.
The following attachment is what I have so far:
and I get the error
Traceback (most recent call last):
File "/Applications/Python Assignments/C15E6_JustinKorn.py", line 58, in
<module>
my_inbox.get_message(i)
NameError: name 'i' is not defined
Please help me.
Thanks,
Justin
