Trimester : T1 2019
Unit Code : HS1031
Unit Title : Introduction to Programming
Assessment Type : Group Assignment
Assessment Title : Assignment II
Purpose of the assessment (with ULO Mapping) : Assess student’s ability to analyse programming problems and design and implement solutions as part of a developer team.
Weight : 15 % of the total assessments
Total Marks : 15
Word limit : N/A
Submission Guidelines : There are five questions in this assignment which require you to write and submit five Python scripts. Similar to what you did in assignment I, please save each script in two different formats: .py and .txt prior to submission. For example, for the first question you need to submit unique.py and unique.txt. Code must be appropriately commented. Make sure to add comments at each segment of your code to explain what it does. You are allowed to use built-in library functions or methods if required. Make sure that your code runs successfully for all possible entries. Try to approach the solution with the least number of steps. Your code must be clear, logical, and easy to understand. All work must be submitted to Blackboard. You are encouraged to avoid last minute submission so that you do not run into technical problems. You can only submit once. Thus, ensure that your work is final prior to submission. This is a group project. Please make sure to divide tasks equally among the group. Group members need to collaborate to make sure that all programs run successfully and are appropriately commented.

Assignment I Specifications

Purpose :

This assignment evaluates your understanding of basic programming principles using Python programming language. In particular, this assignment assesses your ability to develop algorithms to solve simple problems, successfully develop and run python programs, and your ability to write meaningful comments when required. The assignment also provides a platform for students to work together in groups to develop solutions, which resembles how complex programming problems are solved in real-life.

Marking criteria

Appropriate commenting : 5%
Sound logic : 5%
Code running successfully : 5%
TOTAL Weight : 15%
Assessment Feedback to the Student :

Write a program unique.py. The program takes as an input a text file. Your program should print all the unique words in the file in alphabetical order.
Write a program named frequency.py. The program takes as an input a text file. Your program should print all the unique words in the file and their frequencies in alphabetical order.
Define a function conversion.py which takes a decimal number as an input, and returns its representation in a given base as a string (i.e. binary, octal, or hexadecimal string). The function uses a look-up table (dictionary) to map decimal integers to digits in the targeted base. For your convenience, the look-up table is provided below. A main function with test statements are also provided. Hint: figure out how base 10 can be converted to other bases, then write the algorithm.
lookUp = {0 : '0', 1 : '1', 2 : '2', 3 : '3', 4 :'4', 5 : '5', 6 : '6', 7 : '7', 8 : '8', 9 : '9', 10 : 'A', 11 : 'B', 12 : 'C', 13 : 'D', 14 : 'E', 15 : 'F'}

def main():
"""Tests the function."""
print(decimalToRep(10, 10))
print(decimalToRep(10, 8))
print(decimalToRep(10, 2))
print(decimalToRep(10, 16))

# The entry point for program execution
if __name__ == "__main__":
  main()

A list is said to be sorted ascendingly if it is either empty or if each item (except the last one) is less than or equal to the item prior to it. Define a function sorted.py which takes a list as an input and returns True if the list is sorted and False otherwise.
Define a function myRange.py, which behaves like the standard range function in python and takes both required and optional arguments. Do not use the standard Python’s range function in your solution. You need to develop your own range function. Read Python’s help on the standard range function to understand its arguments. Assign None as a default value for the two optional arguments. If the two optional arguments equal None, that means the range function has been called with just the stop value. If only the third argument equals None, this means the function has been called with both, the start and stop values. Therefore, the first part of your code determines what the parameters are while the rest of the code uses these parameters to build-up a list by counting up or down.
