Question

- Create a single module file with at least one class definition. It should have at least three attributes and two methods. At least one of the methods needs to take an argument to change how it behaves. (Does not have to be biologically-related)

- Create a test script which uses and shows off the features of your module.

Example given to us:

A student might have created a fasta.py module with an ‘Entry’ class. That class might have attributes ‘id’, ‘title’ and ‘sequence’, then methods like ‘print_sequence(width=80)’ and ‘reverse_complement()’.

Answer 1

The main module has a class named Student and saves the file as fasta.py

The code will look like this

class Student ): # constructor to initialize the object # the object has three attributes name, age and mark. def _init (self, name, age, courses) self.name name self.ageage self.courses courses # method to update the student course with newcourse as argument def update course (self, new course): - self.courses.append (new_course) # method to display the courses def show courses (self): for course in self.courses: print course

In order to test the module, another file is created say test.py and create the object of the class and test the behaves. The test.py will is attached below.

from fasta import Student objStudent 'RAJU', 15, ['python', 'java', ) print Before course update' obj.show courses () obj.update_course ('data structure') print 'nAfter course update' obj.show courses ()

The screenshot of the output is
