Each problem requires you to ''edit'' a program that is partly written, and available on Moodle, so that the output of your edited program matches exactly the output specified in the problem.  You will find this assignment in the CSC111 section of your Moodle account.

Each problem requires you to ''copy'' an incomplete program into IDLE, and then ''edit'' it so that the output of your edited program matches '''exactly''' the output specified in the problem.  You will find this assignment in the CSC111 section of your Moodle account.   
  
 
There may be many different ways to edit a program to make it output the one specified in the problem.  In general, if you have a choice between several possible modifications, pick the one that is the simplest.  Do not try to rewrite the program, but keep its structure.  It is acceptable to add new statements in some problems.  You must '''evaluate''' each program on Moodle to receive a grade for it.  Make sure you evaluate your programs before the deadline, otherwise you will not receive a grade.  Remember that no extensions are given in this class!

'''Grading''':  The homework assignments count for a total of 40% of the final grade.  Since there will be approximately 11 assignments this semester, each one will count for roughly 40/11 or 3.9% of the final grade.  Homework 1 contains 10 problems; therefore each one counts for approximately 0.039% of the final grade.  The programs are graded 0 or 100, depending on whether its output is exactly the one required, or not.

--D. Thiebaut (talk) 14:45, 25 January 2015 (EST)


In this assignment is due on 2/3/15 at 11:55 p.m.

Each problem requires you to copy an incomplete program into IDLE, and then edit it so that the output of your edited program matches exactly the output specified in the problem. You will find this assignment in the CSC111 section of your Moodle account.

There may be many different ways to edit a program to make it output the one specified in the problem. In general, if you have a choice between several possible modifications, pick the one that is the simplest. Do not try to rewrite the program, but keep its structure. It is acceptable to add new statements in some problems. You must evaluate each program on Moodle to receive a grade for it. Make sure you evaluate your programs before the deadline, otherwise you will not receive a grade. Remember that no extensions are given in this class!

Grading: The homework assignments count for a total of 40% of the final grade. Since there will be approximately 11 assignments this semester, each one will count for roughly 40/11 or 3.9% of the final grade. Homework 1 contains 10 problems; therefore each one counts for approximately 0.039% of the final grade. The programs are graded 0 or 100, depending on whether its output is exactly the one required, or not.



Problem #1


Open IDLE on your computer and type in the incomplete program shown below. Modify it until you get it to show the output shown in the second column, below. When you are satisfied your program runs correctly, submit it to Moodle, in the HW 1 P 1 section:

Incomplete program Output 
# Homework 1, Problem 1

age = 1
name = "Alex"
year = 2015

print( "--", year )
print( name, "is", "and was born in" )

-- 2015 --
Alex is 20 years old, and was born in 1995
Alex will be 25 in 2020.


Make sure you evaluate the program and receive a grade for it, otherwise your work will not be counted toward the homework grade!

Problem #2


Open IDLE on your computer and type in the incomplete program shown below. Modify it until you get it to show the output shown in the second column, below. When you are satisfied your program runs correctly, submit it to Moodle, in the HW 1 P 2 section:

Incomplete program Output 
# Homework 1, Problem 2

college = "Smith College"
bar = "-" * len( college )
name = "Fiona"
print( bar )
print( college )

-------------
Smith College
Fiona
-------------


Make sure you evaluate the program and receive a grade for it, otherwise your work will not be counted toward the homework grade!

Problem #3


Be sure to read Chapter 1, Section 6 in Zelle before starting. Then, open IDLE on your computer and type in the incomplete program shown below. Modify it until you get it to show the output shown in the second column, below. When you are satisfied your program runs correctly, submit it to Moodle, in the HW 1 PB 3 section:

Incomplete program Output 
# Homework 1, Problem 3 (read Section 1.6 in Zelle)

def greet( person ):
    print( person )
