Study Notes
Python Programming Concepts
- An ordered set of instructions for a computer is called an algorithm, pseudocode, or program.
- A computer understands machine language (binary code).
- Python uses an interpreter to convert high-level code to machine language.
- Python is an open-source language developed by Guido Van Rossum.
Python Data Types and Variables
- Python is case sensitive.
- Keywords in Python are lowercase.
- To run Python programs, use Ctrl+R or F6/F5.
- Identifiers are used to name variables, functions, etc. They cannot start with numbers and must not be keywords.
- Identifiers cannot include special symbols.
Python Comments and Statements
- Comments are used to explain code (e.g.,
# this is a comment). - Single-line comments start with
#. - Multi-line comments use triple quotes (
"""Docstring"""). - Python code can use interactive or script mode.
- By default, Python files have a
.pyextension. - Python files are saved in the Python installation folder or the user's desktop.
Python Data Structures and Operations
- Python supports various data types, including integers, floats, strings, booleans.
- Variables hold data values.
- Data types like integers, floats, and other types, can hold single values.
- An operand in math or logic is a value subjected to an operation.
- An operator is a symbol used in mathematical or logical operations.
Python Operators and Keywords
- Keywords are reserved words in Python.
- Operators perform operations on values.
- An identifier is a name given to a variable in a program.
- Literals represent fixed-value data items, like numbers or strings.
- Python has different data types such as integers, floats, strings, lists, tuples, and dictionaries.
Python Input and Output
- The
input()function in Python takes input from the user. - The input can be a number or a string.
Python Features and Properties
- Python's case sensitivity is crucial when working with variables and keywords.
- Key features include being an open-source language; not case-sensitive codeblocks using brackets; Python is not proprietary software.
