Study Notes
Basic Python Concepts
- Python is a high-level programming language used to execute tasks
- Computer understands instructions written in binary (0s and 1s) called machine language
- Python converts high-level code into machine language using an interpreter or compiler
- Python is open-source, case-sensitive, and based on ABC language, developed by Guido van Rossum
- Case sensitivity is important; Python differentiates between upper and lower-case
- Programs requiring execution are saved using .py file extension
- Keywords are reserved words with specific meanings in Python and cannot be used as identifiers (e.g.,
if,else,for) - Identifiers are names given to variables, functions, etc., and follow these rules:
- Start with letters or underscore (_), followed by letters, numbers, and underscores
Python Features
- Interpreted language: Each line is executed immediately
- Interactive mode: Allows execution of a single line or block of code
- Script mode: Runs a sequence of commands from a file (.py extension)
- Keywords: Reserved words in Python; have predefined special meanings
input(): Function to get user input, which may be an integer, string or floating point values, treated as a string- Identifiers can be of any length
- Avoid special symbols (!, @, #)
- Comments allow for descriptions within Python code, which are ignored by the interpreter
- Single line comments start with #
- Multi-line comments use triple quotes(""" """)
- Python data types (e.g., integers, floats, strings, booleans, complex numbers) have specific meanings
- Data sequences, like strings and lists, can be processed
- Identifiers cannot be keywords (reserved words)
Python Data Types
- Integers (whole numbers)
- Floating-point numbers (numbers with decimals)
- Strings (sequences of characters)
- Boolean (True/False)
- Complex numbers
- Data sequences:
- Strings
- Lists
- Keywords are used often in conditional statements (if/elif/else), loops (for/while), and functions (def)
Python Operators
- Operators perform operations on values
- Operators can be arithmetic, comparison, logical and others.
- Binary operators work on two operands (values)
- Operators can be arithmetic, comparison, logical and others.
