What is the primary characteristic of Python variables?

Variables are created as soon as a value is assigned to them.

What are the 5 Variable name rules in Python?

1. can only contain letters, numbers, or an underscore.

2. MUST start with either a letter or underscore

3. Cannot start with a number

4. Cannot contain special characters.

5. Cannot be a Python keyword (such as: and, as, def, else, etc)

What are the 3 common naming conventions used in Python, and what is their format?

Camel case: each word, except for the first word, starts with a capital letter

Pascal case: each word starts with a capital letter

Snake case: each word in the variable is separated by an underscore.

What happens if the number of variables is not equal to the number of values in a Python assignment statement?

An error will occur

What does unpacking involve in Python?

Extracting elements from iterable objects and assigning them to individual variables

What is the result of using the '+' operator to output multiple Python variables of different types?

A Python error occurs. (must use variables of the same type)

How can multiple Python variables of different types be output using the print() function?

By separating each variable with a comma

What is the scope of a variable that is defined inside a function in Python?

Local Scope

How can a global variable be created inside a function in Python?

By declaring the variable with the 'global' keyword

What is a characteristic of Python as a dynamically-typed language?

The interpreter determines the type of variable during runtime

Which Python data type represents an ordered, mutable sequence?

'list'

What are the 3 sequence types in Python? what do they represent/look like?

list: Ordered, mutable sequence; [1,23]

tuple: Ordered, immutable sequence; (1,2,3)

range: represents a range of values; e.g. range(5)

What are the characteristics of a set?

Unordered, mutable collection of unique elements. {1,2,3}

what is a dictionary mapping type?

an unordered collection of key-value pairs.

my_dict = {'key':'value', 'name':'John'}

What happens when an operation is performed that involves both an int and a float in Python?

the result is automatically promoted to a 'float'

What does the 'round(x, n) function do in Python?

it rounds 'x' to 'n' decimal places

What are the two main escape characters?

\n : new line

\t : for a tab

What are the 3 components of a string slice?

string [start:stop:step]

· Start: the index from which the slicing begins (inclusive)

· Stop: the index at which the slicing ends (exclusive)

· Step (optional): The step or stride between characters.

What does the string slicing operation 'text {::-1] do where text = "Hello, Python!"?

It reverses the string.

The 'step' portion of the slice is negative, indicating the stride between characters is reversed.

What does the 'strip()' method do in Python?

It removes leading and trailing whitespaces from a string

what does the += operator do in Python string manipulation?

It is used as a shorthand for concatenation and assignment

What are truthy and falsy values in Python?

Truthy values are non-zero numbers and non-empty strings.

Falsy values are zero, None, and empty strings

What is the purpose of the // operator in Python?

It performs floor division operation;

performs division and rounds down to the nearest whole number and discards the decimal part

What is the purpose of the modulus operation '%' in Python?

It returns the remainder of the division of two numbers.

What does the arithmatic operator **= do?

It take the exponent of the value applied to it.

Consider the following Python code:

colors = ['red', 'blue', 'green'] colors.insert(1, 'yellow')

What will be the value of colors after executing this code?

['red', 'yellow', 'blue', 'green']

when using the .insert(), it doesn't replace the value in that position, it inserts into that place.

When would I use extend() vs append()?

extend() is used for adding multiple values from an iterable

append() is used for adding a single element to the end (even if it's a list)

my_list = [1, 2, 3] my_list.append([4, 5]) # Appending a list as a single element

print(my_list) # Output: [1, 2, 3, [4, 5]]

What does the pop() method do?

It removes an item at the specified index position.

example:

devices = ['router1', 'switch2', 'firewall3']

removed_device = devices.pop(1)

This removes 'switch2' from devices since it is in index 1 position, and now it added to "removed_device.

What is a 'shallow copy' of a list in Python?

A copy of the list where changes to the copied list do not affect the original list.

What is the difference between using the '+' operator and the 'extend()' method to concatenate lists in Python?

The '+' operator creates a new list, while the 'extend()' method adds elements to the end of the original list.

What is a significant advantage of using tuples in Python for storing information about network devices?

tuples can be used as keys in dictionaries due to their immutability.

How are items in a tuple accessed?

By placing the index of the item inside square brackets [] after the tuple name
