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'] t(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_d([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 = (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("1n2n3") print using newline characters print( ) print a blank line python 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(( )) display a in console in upper case print(( )) display a in console as lower case print(( )) remove whitespace at beginning and end print(ce("H", "J")) replace a string with another string print(("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. 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!")

It separates a section of code from the rest of the code so that you can do unit testing. If the module is the main program, it will run anything designated as __name__ == __main__. If the module was imported into the main program as a regular module (e.g., with "import"), anything designated __name__ == __main__ will NOT run. This is because when importing the module, the file name will be assigned as __name__. What is polymorphism? the behavior of an operator will depend on the type of operands; for example, * between two integers will result in the product of the integers but one string and one integer will result in the string being repeated (integer) times What is dynamic typing? the interpreter determines the type of objects as the program executes; the programmer does not have to define them What is static typing? programmer must define the type of every variable and every function parameter in the source code What is modular development? dividing a program into separate modules that can be developed and tested separately and then integrated into a single program function stubs function definitions whose statements haven't been written yet; at least one statement is required in a user defined function; can use pass keyword (program continues), return -1 (if should have a return value), print("FIXME"), or raise NotImplementedError (program stops) Easy way to print the contents of list (separated by spaces, no brackets) print(*list) To iterate each element of a list for num in numbers: print(num, end=' ') Can add condition: for num in numbers: if number = 8 print(num, end=' ') What is pass-by-assignment? arguments to functions are passed by object reference Calling a variable without using f-string color = input("Enter a color: ") print("Roses are " + color) If you get an "invalid syntax error," what should you check? that you have not forgotten : also check the line before the erroring line to see if you have the : and have closed ) or } as needed During a loop, create a string, and append it? my_string = ' ' my_string += str(letter) reversed( ) my_string = "hello" rev_string = ' ' for rev in reversed(my_string): rev_string += rev return rev_string Calling a function from a function def functionA(inputA):What does read() do?
