Cоding Questiоns Yоu mаy not use аny concepts (including built-in functions) which we hаve not covered in Modules 1 - 11. You can find all material allowed in this exam at the end of these instructions. Other restrictions apply per function. Use of coding standards and language syntax, type annotations, code clarity, and logic of the solution are part of the grade. You do not need to include main or a docstring, but you do need to include type annotations in the function definition. You should identify tasks that address a specific part of the problem and implement them as helper functions Coding questions are graded for correct syntax, proper use of coding standards, and design, (Use the space bar, not the Tab key to provide indentation) Quiz #3 Notes Data types intfloatstrboollisttuple Type Casting type(value) returns the data type of value>>> type(5) Arithmetic Operators i + j -> The sumi – j -> The differencei * j -> The producti / j -> Divisioni ** j -> i to the power of ji // j -> the quotient when i is divided by ji % j -> the remainder when i is divided by j Relational Operators x > y Is x greater than y?x < y Is x less than y?x >= y Is x greater than or equal to y?x >> len('hello')5>>> len([1, 8, 2, 8])4 y in x: Returns True if y is in sequence x; False otherwise (works on strings and lists)>>> 2 in [1, 8, 2, 8]True>>> "r" in "Penn State"False A-Z: ASCII values = 65 -> 90a-z: ASCII values = 97 -> 122ord(char): Returns an integer with the code for char>>> ord("A")65chr(code): Returns the character with the given code>>> chr(65)'A' abs(value): Returns the magnitude of the given value>>> abs(5.6)5.6>>> abs(-9)9 Slicing Syntax sequence[start : end], end is exclusive List Operations and Methods x.append(y): Adds y at the end of list x>>> lst = [1, 8, 2, 8]>>> lst.append('hi')>>> lst[1, 8, 2, 8, 'hi'] k * x: Returns the list x repeated k times>>> 3 * [0][0, 0, 0] x + y: Returns a new list that contains all elements in both lists>>> [1,2,3] + [2,3,4][1,2,3,2,3,4] pop and del remove the element at position i.>>> lst = [1, 8, 2, 8]>>> lst.pop(1)8>>> del lst[0]>>> lst.pop() # Removes the last element8>>> lst[2] String Operations and Methods k * x: Returns the string x repeated k times>>> 3 * 'hello''hellohellohello' x + y: Returns a new string that contains all elements in both strings>>> 'hello' + 'world''helloworld' Formatted string literals>>> v1='Sam'>>> v2= 5>>> f'{v1} has {v2} coins''Sam has 5 coins' ''.join(sequence): Takes all items in an sequence of strings and joins them into one string:>>> '-'.join(['1', '2', '3'])'1-2-3' split(separator): breaks down a string into a list of substrings using a chosen separator>>> s = "hello,here,there">>> s.split(",")['hello', 'here', 'there']>>> s = "hello here there">>> s.split()['hello', 'here', 'there'] strip(): removes any leading, and trailing whitespaces.>>> s = " hello there ">>> s.strip()'hello there' Dictionary Methods and Operators x[y] = z: Adds key y with value z to the dictionary x[y]: Returns the value with key y in dictionary if exists, raises a KeyError if y is not in dictionary>>> d = {'x': 4, 8: 'c'}>>> d['x']4>>> d['w']KeyError: 'w'x.get(y): Returns the value with key y in dictionary if exists, returns None if y is not in dictionary>>> d = {'x': 4, 8: 'c'}>>> d.get('x')4>>> d.get('w')pop and del remove the pair with given key>>> d = {'x': 4, '8': 'c'}>>> d.pop('x')4>>> del d['8'] Files open(filename,'r'): Open a file for reading. open(filename,'w'): Open a file for writing. open(filename,'a'): Open a file for appending. open(filename,'x'): Creates a file called filename, returns an error if the file existsfilevariable.close(): File use is complete.filevariable.read(): Reads and returns the entire file as a single string.filevariable.readline(): Returns the next line of the file with all text up to and including the newline character.filevariable.readlines(): Returns a list of strings, each representing a single line of the file. filevariable.write(a_string): Add a_string to the end of the file.
It’s the Zоmbie Apоcаlypse, аnd аs the last surviving emplоyee of the Centers for Disease Control and Prevention, it’s up to you to determine the cause and save humankind.
