Biorhythms: Theory & Practice
In this assignment you will provide a Python script which will calculate the Biorhythms for any individual and present the data graphically using libraries and a common algorithm.
Timelines and Expectations:

K2. Recall and use typical programming constructs to design and implement simple software solutions.
K3. Reproduce and adapt commonly used basic algorithms.
K4. Explain the importance of programming style concepts (documentation, mnemonic names, indentation)
S2. Write and implement a solution algorithm using basic programming constructs.
S3. Demonstrate debugging and testing skills whilst writing code.
A1. Develop self-reliance and judgement in adapting algorithms to diverse contexts.
A2. Design and write program solutions to identified problems using accepted design constructs.
Biorhythms were developed by Wilhelm Fließ, a colleague of Sigmund Freud, in the 19th century and
were very popular in the 1970s (Troutman, 1978); despite criticisms they are still used today in fields
such as work safety to sports performance (Arab, Omidvari, & Nasiripour, 2014; Habibi, Mohammadi,
Ghanbary Sartang, & Zeinodini, 2016; Zareian, Rabbani, & Saeedi, 2014).
The theory underlying Biorhythms proposes that, from birth, three cycles: physical, emotional and
intellectual affect our performance. Understanding these cycles can help to optimise our potential.
Although there are many references available, the paper by Troutman (1978) has been attached as an early
(Spend a little time looking at the code at the end of this paper. Consider all the GO TO statements in the code and
how it affects readability. Would this code be easy to modify? Debug? Compare this with the way we write code
today – refer to the 3 structures given by Boehm and Jacopini in the additional material in week 1.)
Your main task is to develop a Python application that can display Biorhythms for any person given
their date of birth and the target date. You should be able to provide the Biorhythms for a suitable
spread around the target date as well.
Two algorithms to determine the day of any date have been provided – you are to implement one of
these in a function which you call in your code to add the day of the week to your graph annotation.
Using a few carefully chosen dates, demonstrate that your day of the week function works correctly.
(Here we don’t use a Python library function for this so that you might better appreciate libraries.)
The last stage is to apply the Biorhythm code that you have implemented. There are many ways to do
this, for example:
Choose a favourite sports person – Roger Federer or Serena Williams for example. How were their
Biorhythms in their last tennis match? Did they win? If not what were their adversary’s Biorhythms
Take a celebrity – a famous actor – Clark Gable or Marilyn Monroe. Clark Gable had a heart attack on
November 5, 1960 and died shortly after. What were his Biorhythms like around this time?
Biorhythms indicate that we are at our peak when all three curves are at their maximum. How often
could we expect to experience this in our lifetimes? 10, 50 or 100 times or more? Modify your code to
Discuss your own ideas with your lecturer or tutor.
A report is to be submitted in this assignment. There is a discussion section in the report in which you
can apply step 6 in the six-step problem solving process and ask the four questions often used in
evaluating a solution.
More details on academic reports are available – please refer to this link:
There are three important parts:
1. General Guide to Writing and Study Skills
This section describes the content of a report – refer to page 34 – Abstract, Table of Contents,
Introduction, Conclusion and so on.
2. General Guide to Referencing
APA referencing style is described in this section – EndNote is also available to students
3. Assignment Layout and Appearance Guidelines
This section describes how the report should appear: margin sizes, fonts, how diagrams and
tables are presented and so on.
While you are encouraged to research and discuss your work with colleagues, the final product must
be all your own work. (Screen shots of a debugger might be useful in explaining how your code

Assignments will be marked on the basis of fulfilment of the requirements and the quality of the work.
In addition to the marking criteria, marks may be deducted for failure to comply with the assignment
requirements, including (but not limited to):
• Incomplete implementation(s), and
• Incomplete submissions (e.g. missing files), and
• Poor spelling and grammar.
You might be asked to demonstrate and explain your work

Plagiarism is the presentation of the expressed thought or work of another person as though it is one’s
own without properly acknowledging that person. You must not allow other students to copy your work
and must take care to safeguard against this happening. More information about the plagiarism policy
