Study Notes
Python Basics
- The
print()statement in Python is used to output text or values to the screen.
Case Sensitivity
- Python is a case-sensitive language, meaning that uppercase and lowercase letters are treated as distinct characters.
- This significance affects variable naming, as
variableandVARIABLEwould be treated as two different variables.
Print Statement and Math Operations
- The
print()statement can be used to display the output of mathematical expressions, such as$5(7 + 3). - The result of using the
print()statement to display$5(7 + 3)would be the calculated value of the expression, which is$5 * 10 = $50.
Python Syntax
- Python's syntax is often compared to the English language, with a focus on readability and simplicity.
- Python's syntax is designed to be easy to understand and write, making it a popular choice for beginners and experienced programmers alike.
IDLE
- Python's IDLE (Integrated DeveLopment Environment) is a basic development environment that comes bundled with Python.
- The main advantage of using IDLE is that it provides a simple and interactive way to write and test Python code.
Comments
- Comments in Python are used to add notes or explanations to the code, and are ignored by the interpreter.
- The significance of comments is that they help make the code more readable and understandable, and can be used to explain complex logic or algorithms.
- A true statement about comments in Python is that they start with the
#symbol and continue until the end of the line. - The purpose of using comments is to add clarity and documentation to the code, making it easier for others (and yourself) to understand the code's purpose and functionality.
Test your knowledge of Python programming basics including features, data types, comments, print statement, variables, input statement, and applications like image processing, network programming, artificial intelligence, machine learning, and web development.
