Introduction to Python Concepts

What is the purpose of the Python interpreter?

• To compile Python code into machine language.

• The purpose of the Python interpreter is to execute Python code.

• To provide a graphical user interface for Python programming.

• To manage Python libraries and dependencies.

Name two features of Python.

• 1. Simple and readable syntax; 2. Extensive standard library.

• No support for object-oriented programming

• Limited standard library

• Complicated and verbose syntax

What is IDLE in the context of Python?

• IDLE is a command-line tool for Python scripting.

• IDLE is a Python framework for web development.

• IDLE is a type of Python library.

• IDLE is the Integrated Development and Learning Environment for Python.

How do you write a comment in Python?

• Use '//' to write a comment in Python.

• Use '/*' to start a comment and '*/' to end it in Python.

• Use '#' to write a comment in Python.

• Use '/* comment */' for comments in Python.

What are keywords in Python? Give an example.

• 'print' is a keyword used for outputting text.

• An example of a keyword in Python is 'def', which is used to define a function.

• 'return' is a keyword that ends a function.

• 'input' is a keyword for taking user input.

What is the difference between a statement and an expression?

• A statement is always true; an expression can be false.

• An expression performs an action; a statement evaluates to a value.

• A statement performs an action; an expression evaluates to a value.

• Both statements and expressions are the same in programming.

Explain the concept of operator precedence in Python.

• Operator precedence in Python dictates the order of operations in expressions, with higher precedence operators evaluated first.

• All operators in Python have the same precedence level.

• Operator precedence only applies to arithmetic operations in Python.

• Operator precedence in Python is irrelevant to expression evaluation.

What is the purpose of the 'input' function in Python?

• To take input from the user and return it as a string.

• To define a function in Python.

• To store data in a variable.

• To perform mathematical calculations.

How do you define a function in Python?

• Use 'function function_name(parameters):' to define a function in Python.

• Functions are defined using 'define function_name(parameters):' in Python.

• Define a function with 'create function_name(parameters):' in Python.

• Use 'def function_name(parameters):' to define a function in Python.

What is recursion in programming?

• Recursion is a method where a function solves a problem by calling itself.

• Recursion is a method of storing data in a database.

• Recursion is when a function is executed only once in a program.

• Recursion is a technique where a function runs in parallel with another function.
