Study Notes
Python Programming Language
- Python is a high-level, interpreted programming language known for its readability and simplicity.
- It is dynamically typed, allowing variable types to change at runtime, making it flexible for developers.
Print Function
- The
print()function outputs text or variables to the console, providing a way to display information to users.
Python Interpreter
- The Python interpreter executes Python code line by line, allowing for immediate feedback during development.
Basic Expressions
- The expression
3 + 7evaluates to10. - The expression
int(2.0)returns2, converting a float to an integer.
Variable Declaration
- Variable declaration in Python is done by assigning a value to a variable name without explicit type declaration.
- For example, in
$x = 7$, the variablexis declared and assigned the integer value7`.
Data Types
- The result of the expression
132323 ** 2is an integer type, representing132323squared. - The result of the expression
3 + 1jis a complex number, specifically(3+1j).
String Operations
- Python allows string concatenation using the
+operator, for example,'Hello' + ' World'results in'Hello World'. - To print the string
'Hello'without quotes, simply useprint('Hello').
Variable Naming Rules
- Variable names in Python must start with a letter or underscore, followed by letters, numbers, or underscores, and are case-sensitive.
String Slicing
- The output of the code snippet
$s = '012345'$, $s[2:]$is2345, which slices the string from index 2 onward.
Interactive Mode Advantages
- Python's interactive mode allows developers to test small code snippets quickly and receive immediate results, enhancing learning and debugging.
Modules
- Modules in Python serve to organize and reuse code, enabling developers to include libraries and functionality in their projects efficiently.
Beginner-Friendly Features
- Python's clear syntax and structure, along with extensive documentation and community support, make it accessible for beginners in programming.
Expressions in Programming
- Expressions in Python evaluate to a value and can involve operations like arithmetic, logical, and string manipulation, essential for creating functionality.
