Study Notes
Introduction to Programming with Python
- Python is a powerful, multi-paradigm, interpreted programming language used by startups and large companies.
- Guido van Rossum created Python and it was first released in 1991.
- Python has two major versions: 2 and 3.
Why Python?
- Python was designed to be an easy and intuitive language, while being as powerful as its competitors.
- Python code is designed to be as understandable as plain English.
- Python is open-source, meaning anyone can contribute to its development.
- Python is suitable for everyday tasks, allowing for short development times.
What is a Computer?
- A computer is a machine capable of performing billions of calculations per second (gigahertz), storing hundreds of gigabytes of data, and interacting with input/output devices.
- Computers only understand instructions given to them.
Computer Main Components
- Central Processing Unit (CPU): Executes instructions, performs calculations, and manages other components.
- Memory (RAM): Temporary storage for data and programs currently being used.
- Secondary Storage (Hard Disk): Long-term storage for operating systems, programs, and user data.
- Input Devices: Provide data to the computer (e.g., keyboard, mouse, scanner).
- Output Devices: Display or present data from the computer (e.g., monitor, printer).
How a Program Works
- The CPU performs simple operations (e.g., adding, subtracting) on data, which are stored as sequences of 0s and 1s.
- Each CPU brand has its own specific instruction set.
- To perform complex tasks, the CPU executes many simple operations in sequence.
Computer Programs and Programming Languages
- A computer program is a set of instructions that a programmer writes to tell a computer what to do.
- Programming languages are used to write computer programs.
- Compilers or Interpreters translate these instructions into machine code that the CPU can execute.
- Compilers translate entire programs into machine code which can be executed later.
- Interpreters directly execute instructions line by line.
Components of a Computer Program
- Programs consist of data, instructions, and a flow of control.
- The flow of control determines the order in which instructions are executed.
- Conditional branching allows programs to make decisions based on data.
- Repetition or iteration allows programs to repeat tasks multiple times.
- Function calls allow programs to organize code into reusable blocks.
High-Level Languages
- High-level languages are easier to use and understand than low-level languages.
- They abstract away the complexity of the CPU, allowing programmers to focus on the logic of their programs.
- Python is a high-level language.
Python Setup
- Download the latest version of Python from https://www.python.org/.
- Install Python on your machine.
- Download Anaconda, which includes Python and Jupyter Notebook, from https://www.anaconda.com/products/individual.
- Install Anaconda on your machine.
- Open Jupyter Notebook from the Windows Start Menu.
