Study Notes
Python 2.0 and 3.0 Overview
- Python 2.0 launched in 2000, introducing garbage collection and features from languages like Haskell.
- Officially reached "end-of-life" in 2020, but Python 2.7 remained popular due to limited third-party library support.
- Python 3.0, released in 2008, aimed to fix design issues; it is not backward compatible with Python 2.7.
- Python 3.x has been widely adopted for new projects.
Importance of Whitespace in Programming
- Whitespace includes any blank space or newline and affects formatting and professionalism in code output.
- Precise formatting is crucial, as small errors (e.g., = vs ==) can lead to significant bugs.
- Example of poor formatting includes misplaced text and lack of newlines, resulting in an unprofessional output.
Computing Fundamentals
- Computers can store terabytes of data on disk while memory typically holds gigabytes.
- Processes involve loading programs from disk into memory for execution.
- Efficient program execution doesn't require disk access if the program is already in memory.
Transistor Technology and Moore's Law
- Transistors, integrated into chips in 1958, have drastically decreased in size and are pivotal to modern computing.
- Moore's Law predicts IC capacity doubles approximately every two years, driving technology advancements.
Scripting Languages and Python's Evolution
- Scripting languages execute programs without compilation, making them easier to use but potentially slower than compiled languages.
- Python was created by Guido van Rossum in the late 1980s, derived from ABC, focusing on simplicity and readability.
- Python 1.0 debuted in 1994 and supported some functional programming constructs from Lisp.
Basics of Programming
- A program is a sequence of instructions executed one at a time, involving input, processing, and output.
- Key concepts include:
- Variables: Named storage locations in memory (e.g., x, y, z).
- Algorithms: Step-by-step instructions to solve problems.
Python Programming Concepts
- Python interpreter executes the code written in Python, while the interactive interpreter allows line-by-line execution.
- Code consists of statements and expressions, with new variables defined via assignments using the = symbol.
- Output is generated using the print() function, and comments in code are marked with # for clarity.
Input and Output in Python
- The print() function outputs text, with strings being sequences of characters enclosed in quotes.
- Use of the end parameter in print() allows control over output formatting to keep items on the same line.
