====== Programming for Data Science A.Y. 2017/18 ======

This is an introductory course to computer programming and related mathematical/logic background for students without a Bachelor in Computer Science or in Computer Engineering. The objective is to smoothly introduce the student to the programming concepts and tools needed for typical data processing and data analysis
tasks. The course consists of lectures and practice in computer labs.

=====Software=====

  * **Python programming:** [[https://www.continuum.io/downloads|Anaconda distribution of Python 3]]. Computers at lab rooms include it both on Linux and Windows OS.
  * **C programing:** either [[https://wiki.gnome.org/Apps/Gedit|gedit]] (or equivalent text editor) and [[https://gcc.gnu.org/|gcc]]. If you do not have gcc on your machine, check next item. Gedit and gcc are available on computers at lab room (Linux only).
  * **gcc compiler:** To be able to compile C programs, you need to have a gcc compiler installed on your machine. If you use Linux....well, why are you still reading? :) If you use macOSX, almost no problems: just install XCode; then from Xcode Preferences > Downloads choose “Command line tool”, and install it as well: you will have gcc on your machine. Finally, for Windows users, you need to install any gcc compiler. You have two options: 
      * (1) install minGW [[http://www.mingw.org/|minGW]]. Once the MinGW Installation Manager has been installed, execute it and install the  whole MinGW package (from the Package menu). After everything has been downloaded and installed, you first need to set the PATH environment variable (see here: [[https://www.computerhope.com/issues/ch000549.htm|set Windows PATH]]); now, you will also have gcc compiler on your machine. 
      * (2) install [[https://sourceforge.net/projects/orwelldevcpp/|DevC++]]: write and save your program, and then compile and run it by accessing the **Execute** menu.
  * **Compile C on lab machines (Windows)** Use DevC++.
  * **Editor for C files** Either use the DevC++ editor, or use [[https://notepad-plus-plus.org/download/v7.5.2.html|Notepad++ ]].
  * **Python/C online** including visualization of memory state [[http://pythontutor.com/|PythonTutor]].

**Next exam (reserved session) will be on Wednesday 4th of April, from 2pm to 6pm, Lab H.**

<html>
<span style="color:red"> IMPORTANT: </span></html> **To be able to solve the C exercises during the exam, you need to use DevC++ installed in the Windows partition of the computers' lab**. Please, read **carefully** the instructions in the Software section above.
