Study Notes
Introduction to Programming Languages
- A program is a set of instructions that tells a computer how to perform a computation.
- Programming languages are used to write programs.
- Python is a popular programming language.
Python
- Created by Guido van Rossum at Centrum Wiskunde & Informatica (CWI) in the Netherlands.
- Released in 1991.
Features of Python
- Easy to learn.
- General-purpose, meaning it can be used for various tasks.
- High-level, meaning it's closer to human language than machine language.
- Platform independent, meaning it can run on different operating systems.
- Requires few lines of code for complex tasks.
- Simple syntax.
- Case-sensitive.
- Interpreted language, meaning it executes code line by line.
- Free to use and distribute.
Applications of Python
- Building websites.
- Programming robots.
- Developing artificial intelligence applications.
- Developing games.
- Performing scientific computations.
Installing Python
- Download from www.python.org/downloads.
- Double-click the .exe file and follow the installation instructions.
Getting Started with Python
-
Interactive Mode: Default mode, launched by typing
Pythonin the terminal. (or by clicking on Start > Scroll down to Python 3.7 > IDLE (Python 3.7)). -
Script Mode: Used for writing longer programs. Create and edit Python files (
.pyextension) using a text editor.
Components of IDLE Python
- Title Bar: Displays the name of the application and the document. Includes minimize, maximize/restore, and close buttons.
-
Menu Bar: Contains menus with options for:
- File: Opening, saving, closing files, exiting IDLE.
- Edit: Cutting, copying, pasting, searching, and replacing text.
- Shell: Working with the interactive mode.
- Debug: Finding and fixing errors in code.
- Options: Configuring IDLE settings.
- Window: Managing open windows.
- Help: Accessing Python documentation.
- Command Prompt: Denoted by '>>>'. It's where you type Python code.
- Status Bar: Indicates the current status of the cursor and provides helpful information.
Working in Interactive Mode
- Instructions are executed line by line.
- Commands are typed after the '>>>' prompt.
- Results or errors are shown immediately.
- Useful for testing small code snippets.
Printing a Message
- The
print()function is used to display output on the screen. - Example:
This will print "Hello World" on the screen.>>> print("Hello World")
Note About Case Sensitivity
- Python is case-sensitive, meaning
print(lower case) andPrint(upper case) are different.
