Write a function argument_count that accepts an integer i, followed by any number of additional arguments. The function should returnTrue if the value given to i is equal to the number of arguments that follows it, and should return False otherwise.
Inside this module, import random and blackout_utils, and define the following global variable, which you should use whenever appropriate: OPERATIONS = ['^', 'x', '/', '+', '-']For full marks, all the following functions must be part of this module: calculate(tokens): Takes one list of tokens as input corresponding to a mathematical equation. The function will evaluate both sides of the equality and return a list of three tokens: the result of the left-hand side (integer), the equals sign (string), and the result of the right-hand side (integer). The equation may contain any of the operations in the OPERATIONS list, as well as opening and closing parentheses. Your function should evaluate both sides of the equation while respecting order of operations (that is, parentheses, followed by exponentiation, then multiplication and division, and then addition and subtraction). Equations may have multiple sets of parentheses and nested parentheses. The contents of the inner-most nested…
What is a stub? Group of answer choices A stub is an inline function with a single line that simply sends a "Hello" message to others, indicating that it has been activated. A stub is a function that has an empty body. It will be developed later. A stub is an inline function with a single line that simply increases the pass in value by one. A stub is a function with a single line that simply prints the name of the function, indicating that it has been activated. A stub is a short function that will generate an error message.
Write a program that calculates the balance of a checking account at the end of a three- month period. It should ask the user for the starting balance. Then a loop (for loop is recommended) should iterate once for every month in the period, performing the followi 1. Ask the user for the total amount deposited into the account during that month. Do n accept negative number. This deposit should be added to the current balance to make current balance is up to date. 2. Ask the user for the total amount withdrawn from the account during that month. Do accept negative amount or amount greater than the current balance. The withdrawal amount should be subtracted from current balance, so current balance is up to date. 3. Update the total deposit. 4. Update the total withdrawal After the last iteration, the program should display the following information: 1. starting balance at the beginning of the three-month 2. total deposits/withdrawals made during the three-month period 3. final balance…
vowelIndex Write a function vowelIndex that accepts a word (a str) as an argument and returns the index of the first vowel in the word. If there is no vowel, -1 is returned. For this problem, both upper and lower case vowels count, and 'y' is not considered to be a vowel. Sample usage: >>> vowelIndex('hello') 1 >>> vowelIndex('string') 3 >>> vowelIndex('string') 3 >>> vowelIndex('BUY') 1 >>> vowelIndex('APPLE') 0 >>> vowelIndex('nymphly') -1 >>> vowelIndex('string')==3 True >>> vowel Index ('nymphly')==-1 True

For each function, describe what it actually does when called with a string argument. If it does not correctly check for lowercase letters, give an example argument that produces incorrect results, and describe why the result is incorrect. # 1 def any_lowercase1(s): for c in s: if c.islower(): return True else: return False # 2 def any_lowercase2(s): for c in s: if 'c'.islower(): return 'True' else: return 'False' # 3 def any_lowercase3(s): for c in s: flag = c.islower() return flag # 4 def any_lowercase4(s): flag = False for c in s: flag = flag or c.islower() return flag # 5 def any_lowercase5(s): for c in s: if not c.islower(): return False return True The code and its output must be explained technically whenever asked. The explanation can be provided before or after the code, or in the form of code comments within…
Write a function named contains-double in Scheme that takes a list as input and returns true if an item every appears twice in a row. You may assume the list is flat (i.e., no nested lists).
def square(x): return x * X def halve(x): return x // 2 def twice(f,x): """Apply f to the result of applying f to x >>> twice (square,3) 81 >>> twice (square, 4) 256 >>> twice (halve, 32) 8 >>> twice (halve, 80) 20 *** YOUR CODE HERE ***"

Python without Def function Problem Statement Define and implement a function time_delta that takes two string parameters (time1 and time2) and returns the difference between them (as a string). You may assume that the second time will always be after the first time, both times will always be on the same date, and military time will be used (no a.m. or p.m.). Examples time_delta(04:15:36, 16:35:27) ➞ (12:19:51) time_delta(02:06:05, 06:09:10) ➞ (04:03:05) Sample Input 1 "04:15:36" "16:35:27" Sample Output 1 "12:19:51"
in c programing with User-Defined Functions Remove all non-alphabetic characters Write a program that removes all non-alphabetic characters from the given input. Assume the input string will not exceed 50 characters. Ex: If the input is: -Hello, 1 world$! the output is: Helloworld The program must define and call a function named RemoveNonAlpha that takes two strings as parameters: userString and userStringAlphaOnly. userString is the user specified string from the program input. Function RemoveNonAlpha() then assigns userStringAlphaOnly with the user specified string without any non-alphabetic characters.void RemoveNonAlpha(char userString[], char userStringAlphaOnly[])
