Study Notes

Python Overview

Python is a high-level programming language, meaning it's designed to be easier for humans to read than for computers to read.
Development of Python began in the 1980s.
Python was released in the 1990s.
Python's development aimed to enhance readability and thus, ease of learning.

Python Syntax

Python is a case-sensitive language.
Whitespace is significant in Python syntax; the number of spaces, line breaks, and tabs at the beginning of a line are relevant.
Colons define the scope of control structures and functions.
Variable and function names typically follow the snake_case convention (e.g., my_variable, get_data).
Python keywords include return, global, for, if/elif/else, while, def.

Python Functions

Functions are reusable blocks of code, creating logically separate and reusable ideas.
Defining a function uses the def keyword, followed by a name, parentheses, and a colon.
Functions can accept arguments and return values.

Variables and Data Types

Variables are assigned values (e.g., my_num = 4).
Python is a duck-typed language (type checking occurs at runtime).
Common data types include booleans, strings, integers, and floats.

Control Structures

Loops repeat code blocks.
for loops iterate a specified number of times.
while loops iterate until a condition is met or changes.
if/elif/else statements execute code based on conditions that evaluate to boolean values.
Operators used in conditions include ==, !=, >.
