Study Notes

Python Programming Language

Python is a popular programming language created by Guido van Rossum, released in 1991
Used for web development (server-side), software development, mathematics, and system scripting
Versatile, used for web application creation, software workflows, database interactions, handling large datasets, and complex math calculations
Python code runs quickly, due to the interpreter system (code executes immediately)
Suitable for prototyping and production-ready software development

Python Capabilities

Operates on various platforms (Windows, Mac, Linux, Raspberry Pi)
Simple syntax, resembling the English language, with influence from mathematics
Allows for concise code writing, using fewer lines than other languages
Offer flexibility in programming styles (procedural, object-oriented, or functional)

Python Syntax Differences

Uses newlines to complete commands, unlike other languages that use semicolons or parentheses
Employs indentation to define program blocks, such as loops, functions, and classes (instead of curly brackets in other languages)

Python Data Types

Python has different built-in data types to store various data:
- Text Type: str
- Numeric Types: int, float, complex
- Sequence Types: list, tuple, range
- Mapping Type: dict
- Set Types: set, frozenset
- Boolean Type: bool
- Binary Types: bytes, bytearray, memoryview
Variables are named, and data is assigned to them in the code
Indentation is vital for Python code blocks, unlike other languages where it's optional for readability

Comments in Python

Comments start with a '#' symbol, and Python ignores the rest of the line as a comment
Comments can be used to explain or document Python code for clarity
Multiline comments also exist (using triple quotes `""" """)

Strings and Multiline Strings

Python strings are defined using single quotes (' ') or double quotes (" ")
Multiline strings are defined using triple quotes (''' ''' or """ """) to span multiple lines within a string
