A function is a block of code that performs a specific task. It takes inputs, called arguments, performs some operations, and then returns an output. Functions are reusable and help to break down complex problems into smaller, manageable parts.

The key difference lies in the flexibility of data types. In static typing, the data type of a variable is fixed at the time of declaration, limiting it to specific values throughout the program. In dynamic typing, the data type is determined at runtime, allowing variables to hold diverse values without explicit type declaration.

<p>Use a <code>while</code> loop when you need to repeatedly execute code until a specific condition is met, and you don't know in advance how many times the loop needs to run. This is contrast to a <code>for</code> loop, which iterates a fixed number of times based on a range or an iterable object.</p> Signup and view all the answers

<p>Hardcoding refers to embedding specific values or parameters directly into the code, rather than making them dynamic and adaptable to different situations. This is generally discouraged because it makes the code inflexible, difficult to maintain, and prone to errors when circumstances change.</p> Signup and view all the answers

<p>In Python, <code>=</code> is the assignment operator, used to assign a value to a variable. <code>==</code> is the comparison operator, used to check if two values are equal. The <code>=</code> operator stores a value in a variable, while the <code>==</code> operator returns <code>True</code> if the values are equal and <code>False</code> otherwise.</p> Signup and view all the answers

<p>Dot notation is a syntax used in Python to access attributes or methods (internal functions) of objects, including variables. It involves separating the object name and the attribute or method name by a dot (<code>.</code>). For example, <code>variable.method()</code> calls the <code>method()</code> function on the <code>variable</code> object.</p> Signup and view all the answers

<p>Dictionaries in Python are data structures that allow you to store key-value pairs. Each key is unique, and it maps to a corresponding value. Dictionaries are enclosed within curly braces <code>{}</code>, and key-value pairs are separated by colons <code>:</code>.</p> Signup and view all the answers
