ANSWER The interpreter determines the type of variable during runtime Q. Which Python data type represents an ordered, mutable sequence? ANSWER '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 print(10 > 9) print(10 == 9) print (10 < 9) Boolean print(bool("Hello")) print(bool("15")) print(bool(x)) Boolean examples of True print(bool(False)) print( ) print(0) Boolean examples of False print(isinstance(x, int)) determine if an object is of a certain data type int( ) casts an integer from an integer literal, float literal, or string literal float( ) casts a float from an integer literal, a float literal, or a string literal str( ) casts a string from strings, integer literals, or a float literals print("text") outputs text to the console print("text", end=" ") print("more text") will end with a space and continue on the same line ("text more text") print("Wage", wage) comma will print both items with a space between them print(variable) prints the value of the variable print("1\n2\n3") print using newline characters print( ) print a blank line python file.py run a script file random function there is no random function, but there is a random module (import random) for x in "bananas": print(x) strings are arrays, so this will loop through the characters in "bananas" variable=input( ) assign text entered by the user to a variable; input is always a string variable = int(input) convert user input into an integer hourly_wage = int(input("Enter hourly wage: ")) display text prompt (Enter hourly wage) to request input from user and convert to integer print(a.upper( )) display a in console in upper case print(a.lower( )) display a in console as lower case print(a.strip( )) remove whitespace at beginning and end print(a.replace("H", "J")) replace a string with another string print(a.split("b")) split string at specified character c=a+b print(c) concatenate (combine) two strings a=(f"My name is John, I am {age}") print(a) f-string; { } is the placeholder/modifier a = 85.8756 b = format(a, ".2f") print(b) modifier to format the value to 2 decimal places (85.88) price = 85.87562649 b = f"Price: ${price:.2f}" print(b) f-string with placeholder for price and modifier to format value to 2 decimal places (Price: $85.88) What built-in data type is used when you assign text to your variable? str x = "Hello, World!" x = str("Hello, World!") What built-in data type is used when you assign a numeric value to your variable? int x = 20 x = int(20) float x = 20.5 x = float(20.5) complex x = 1j x = complex(1j) What built-in data type is used when you assign a sequence to your variable? list x = ["apple", "banana", "cherry"] x = list(("apple", "banana", "cherry")) tuple x = ("apple", "banana", "cherry") x = tuple(("apple", "banana", "cherry")) range x = range(6) What is the difference between a list and a tuple? list = collection of values tuple = ordered and unchangeable What built-in data type is used when you assign a mapping to your variable? dict x = {"name" : "John", "age" : 36} x = dict(name="John", age=36) What built-in data type is used when you assign a set to your variable? set x = {"apple", "banana", "cherry"} x = set(("apple", "banana", "cherry")) frozenset x = frozenset({"apple", "banana", "cherry"}) x = frozenset(("apple", "banana", "cherry")) What built-in data type is used when you assign a boolean to your variable? bool x = True x = bool(5) What built-in data type is used when you assign binary to your variable? bytes x = b"Hello" x = bytes(5) bytearray x = bytearray(5) memoryview x = memoryview(bytes(5)) What built-in data type is used when you assign the value none to your variable? nonetype x = none What is Syntax Error? contains invalid code that cannot be understood What is Indentation Error? lines of the program are not properly indented What is a Value Error? invalid value is used (e.g., int(three)) What is a Name Error? program tries to use a variable that does not exist What is a Type Error? operation uses incorrect types (e.g. int(5) + string(four)) How do you check which version of Python editor you have? import sys print(sys.version) How do you edit, save, and run a Python file? edit = can edit in a text editor save = save as file.py run = in command prompt, type file.py Can you run Python in the Command Line? type python or py you will see Python version information and >>> when you are finished, type exit( ) What is unique about Python script formatting? relies on indentation (whitespace) to define scope instead of curly brackets Which Python datatypes are used to store arrays? list, tuple, set, and dictionary Which Python datatypes allow arrays with duplicates? list and tuple Which Python datatypes are for ordered arrays? list, tuple, dictionary Which Python datatypes are unchangeable? tuple and set What kind of variable would x = [ ] result in? list How do you determine how many items are in a list? print(len(yourlist)) What are some characteristics of a list? ordered; changeable; allows duplicate values; new values added to the end of the list; indexed (first value if 0, second value is 1, etc.); values can be any datatype (and a mix of datatypes) What are some characteristics of a tuple? ordered; unchangeable; allows duplicate values What are some characteristics of a set? unordered; unchangeable (you can add or remove items, but you cannot change an item); unindexed What are some characteristics of a dictationary? ordered; changeable; no duplicates How do you verify the type of an object? print(type(myobject)) What is an integer? positive or negative whole number of unlimited length What is a float? positive or negative number with a decimal; can also be a scientific number with an e What is a complex number? a number with an imaginary part represented by a j Can you convert a complex number into another number type? no Can you convert a number into a complex number? yes a = complex(x) Can you generate random numbers in Python? no random function, but there is a random module import random print(random.randrange(1,10)) What are the arithmetic operators in Python? + - * / % modulus (remainder) ** exponentiation // floor division (round down to nearest whole number) What is an assignment operator? used to assign values to variables if x = 5 what is x += 3 8 if x = 5 what is x -= 2 3 if x = 5 what is x *= 3 15 [Show Less]
