This github repo contains all the material needed for the practical task.
You are expected to:
- clone or download this github repo locally
- read this documentation
- solve the two tasks, using the programming language of your choice (among Python, Fortran)
- comment on your work and answer questions
Your work will be projected overhead for you and the whole jury to see. You can address comprehension questions to the jury anytime.
You can use google, stackoverflow, or any other online resource you might find useful.
You can not message a friend to help you solve the task.
You have a choice of operating system:
- linux (ubuntu 18 LTS)
- Windows VM
A special account "candidat" has been created on each OS.
For storing your work, you will use a specific directory:
- "Candidat" for linux (in the home directory)
- The same directory shared with the Windows VM as the Z: drive (also named Candidat)
In either operating system, the system is pre-loaded with, among others:
- Notepad++/Geany
- VSCode
- git command line
- python 3
- C++, Fortran (gcc compilers)
Shortcuts for accessing these tools have been attached to either the menu bar (linux) or the task bar (Windows). There is also a shortcut for Firefox.
Identity.txt is a file that contains tab-separated text, over 4 columns. The first line contains the name of the variables.
Here are the first 5 lines of the file:
#name age country city Sarah 18 England Manchester Tom 17 Germany Friburg tim 25 germany berlin Pierre 32 FRANCE Narbonne ...
A. In the language of your choice (Fortran/Python) write a program that list for each country, the number of people and their mean age. The expected output should look like this:
country persons_nb mean_age 1 ENGLAND 1 18.0 3 FRANCE 2 36.5 2 GERMANY 2 21.0 4 ITALY 1 29.0
B. Add at least three lines to the file, save and run the code again
C. Commit your changes to your local branch
We produced a code implementing the same functionality both in Python and Fortran.
You can find the code in the files:
Python: code_review.py
Fortran: code_review.f90, tools.f90
Using the file in the language of your choice, please:
- read the code
- what does it do? add the documentation to the function with a comment
- add an example with a print statement
- commit your changes to your local branch
