Grading guidelines:
2. Break-up of Credits will be as follows:
(a) Percentage of features implemented: 50%
(b) Aesthetics and intuitiveness: 30%
(c) Whether reasonably able to answer questions: 20%
Total marks: 70

Problem 1

20 marks Create a GUI program which evaluates an input single variable function within a specified range of the input values, and creates a plot of the function, and displays in the window.

Problem 2
60 marks Consider a social network application where there are:
– Users: identified by unique user id (String)
– Groups: which are sets of users who are members of the group. The group is identified by a unique group id.
– Contacts: A list of other users who are in the contact list of a given user. – Posts: A string and / or an image which can be posted by the user.

Like in a social network, posts of users can be to a contact or a group. All posts to a group appear in the incoming messages list for all members of the group. All direct posts from a contact also appear as incoming messages. For this current assignment, the list of users, their contacts, and the list of groups is given as an input from a file (named social_network.txt) of the following format:

# users
<user_id1: contact_user1, contact_user2, …>
…
<user_idn: contact_user1, contact_user2, …>
#groups
<group_id1: member1, member2, …>
…
<group_idn: member1, member2, …>

There are four visual modules to be displayed on the screen. Each module displays information pertaining to a current user. The information in the modules should change dynamically as the user changes. The modules are:
– A module to display incoming messages. The text of the message and the image (if any) should both be displayed, formatted appropriately.
– A module to display existing contacts.
– A module to display groups of which the current user is member of.
– A module to compose and post messages. This should also include the Additionally, there should be a droplist / menu for selecting the current user.

Write a python program which implements the above mentioned functionality using TKinter GUI toolkit in python.
