Study Notes
Introduction to Programming
- The course introduces programming concepts focusing on the Python programming language.
- Python is a scripting language that is interpreted by a console.
- You can write and execute Python code interactively through a console, or create scripts using the '.py' extension.
- Python can be installed from the official website: https://www.python.org/
- Development kits for Python are available at: https://www.python.org/downloads/
- The course uses IPython NoteBook for web-based interactive coding: http://mooc.lrde.epita.fr/notebooks/Untitled1.ipynb
Python Basics
- Python offers interactive mode for testing basic arithmetic, syntax, and text manipulations.
- There are different data types in Python including integers, floats(decimals), strings, and booleans.
- Python's 'integers' occupy varying memory space depending on the number's value.
- Python uses dynamic typing, meaning you don't need to explicitly define the type of a variable.
- Type conversions happen implicitly in Python.
- You can determine the size of a variable using 'sys.getsizeof(a)' after importing 'sys'.
- The documentation for Python built-in types is here: https://docs.python.org/3/library/stdtypes.html
- There is a course resource for further learning about Python types: http://fr.wikibooks.org/wiki/Programmation_Python/Type
Variables
- Variables in Python store values in memory.
- Variable names are created using letters, numbers and underscores.
- Variable names cannot start with a number.
- Using descriptive variable names that reflect their purpose makes code more readable.
- You can use short variable names for shorter programs and longer names for more complex programs.
