Checking the Length of a List in Python

• The valid method to check the length of a list in Python is by using the len() function.

Inserting an Element at a Specific Index in a List in Python

• The correct way to insert an element at a specific index in a list in Python is by using the insert() method.

Data Types in Python

• A list is a data type that is used to store multiple items in a single variable, and is ordered, changeable, and allows duplicate values.

Creating a Tuple in Python

• The correct way to create a tuple in Python is by enclosing the elements in parentheses ().

Characteristics of Tuples in Python

• Tuples are ordered and unchangeable data types.

Accessing Tuple Elements in Python

• The output of the code thistuple = ('apple', 'banana', 'cherry') print(thistuple[2]) is cherry, which is the element at index 2 in the tuple.

Data Types in Python

• A set is a data type that allows duplicates and is unordered.

Accessing Dictionary Elements in Python

Calling a Function with Arguments in Python

• The correct way to call the function my_function with arguments fname='John' and lname='Doe' is by using the syntax my_function(fname='John', lname='Doe').

Function Definitions in Python

• The output of the code my_function('Emil') depends on the definition of the function my_function.
• When you call the function my_function with only one argument, it will execute the function with that argument, but the behavior depends on the function definition.

Using * before the Parameter Name in a Function Definition

• The purpose of using * before the parameter name in a function definition is to allow the function to accept a variable number of arguments.

Sending Arguments to a Function using Key-Value Syntax in Python

• In Python, you can send arguments to a function using the key-value syntax, such as my_function(key1='value1', key2='value2').

Function Calls with Lists in Python

• The output of the code my_function([1, 2, 3]) depends on the definition of the function my_function.

The Return Statement in a Function

• The return statement in a function is used to exit the function and return a value to the caller.

The Pass Statement in Python Function Definitions

• The purpose of the pass statement in Python function definitions is to act as a placeholder, allowing the function to be defined without a body, and avoid a SyntaxError.
