Lab 6: Programming in Python I

In this assignment you will write your first Python program. There are
two parts to the program: (1) print your name, your UCD ID number, and
today's date; (2) compute and print the last 4 BINARY digits (bits) of
your ID (in reverse order).

Note: As before, you can do this assignment either in the computer lab
or on your own computer, if you have one. To do the assignment on your
own computer, you will need to install Python. We strongly recommend
you install Python, and we strongly recommend that you do it this
week. If you have a laptop, you could bring it to lab hours and we
would be happy to help you install Python if you need.

Note: For more detailed instructions on using Python, see pp. 8-11 and
pp. 28-35 of the book.  This lab is easier if you do the reading
beforehand.

Note: The hard part of this assignment is to compute the bits of your
ID (in reverse order).  If you don't remember how to convert decimal
to binary, please review the lecture note on binary number.

Starting up Python:
  Go Start -> All Programs -> Class Software -> Python 2.4 -> IDLE (Python GUI)

  What you see is the Python Interpreter that responses to input one by one.

  Try typing: print "hello world" 

  >>> print "hello world"

  hello world

  >>> 

Writing your Python program:
  Go to File on the Python GUI
  Select New Window

  What you see is a new window (the script window) pop up.

  In the script window, use the print statement to type out your name, your ID, and today's date.

  Use print statement to print out "The last 4 bits of my ID (in reverse order) are"

  Assign the last four digits of your UCD ID (considered as a decimal
  number) to the new variable "ID".  For example, if the last
  four digits of your UCD ID is 0024, then assign 24 to "ID".

  Assign the value ID%2 to the new variable "remainder".

  Assign the value ID/2 to the new variable "result".

  Print the value of "remainder" (= last bit of your UCD ID)

  Assign the value result%2 to the variable "remainder".

  Assign the value result/2 to the variable "result".
 
  Print the value of "remainder (= 2nd-to-last bit of your UCD ID)

  Repeat the last three steps to print the 3rd-to-last bit of your UCD
  ID.  Then repeat them again to print the 4th-to-last bit.

Note: Save your Python program to your Desktop, and name it
  "prog1". It should automatically get the suffix ".py", indicating
  that it is a Python program. In Windows, it will show up in the
  folder with the Python logo. 

Running your Python program: go to Run->Run Module. The program should
  then run immediately, producing the output IN THE IDLE WINDOW, not
  in the script window.

For instance, this is an example of program output that appears in the IDLE window: 

>>>===================RESTART=========================

>>> 

My name is John Joe

My UCD ID is 123456789

Today is 10/29/2007

The last 4 binary digits of my ID (in reverse order) is

Turning in your Program: Use my.ucdavis.edu to turn in the program.  The
program name should be named prog1.py. You do not need to turn in a
hard copy.
