- PHP ATM machines allow 4 or 6 digit PIN codes and PIN codes cannot contain anything but exactly 4 digits or exactly 6 digits. *With user input ($pinNumbers), create a function that takes a string and returns true if the PIN is valid and false if it's not. Examples validatePIN("$1234") ➞ true validatePIN("12345") ➞ false validatePIN("a234") ➞ false validatePIN("") ➞ false Notes ● Some test cases contain special characters. ● Empty strings must return false.The following functions are all intended to check whether a string representing a dna sequence contains any characters that are not 'a','c','g','t', 'A', 'C', 'G', or 'T'. At least some of these functions are wrong. Which ones are correct? A) def valid_dna1(dna): for c in dna: if c in 'acgtACGT': return True else: return False B) def valid_dna3(dna): for c in dna: flag = c in 'acgtACGT' return flag C) def valid_dna4(dna): for c in dna: if not c in 'acgtACGT': return False return True -------------------------------------------------------------------------------------------------------------------------------------------------------- valid_dna1 only valid_dna4 only None of them. valid_dna1, and valid_dna4 onlycapCount.py make a program called capCount.py that has a function that takes in a string and prints the number of capital letters in the first line, then prints the sum of their indices in the second line. The string "hEllo, World" would should look like this: 28
- Create a function which returns the type of triangle, given the side lengths. Return the following values if they match the criteria. • No sides equal: "scalene" • Two sides equal: "isosceles" • All sides equal: "equilateral" • Less or more than 3 sides given: "not a triangle" Examples get_triangle_type([2, 6, 5]) "scalene" get_triangle_type([4, 4, 7]) "isosceles" get_triangle_type([8, 8, 8]) "equilateral" get_triangle_type([3, 5, 5, 2]) → "not a triangle"Tabs to escape in the vertical direction. \n O lb This function returns a non-zero value if char is a letter of the alphabet, and a zero value otherwise. The letter O represents the whole alphabet () A Letter () This is the O isalpha() () This method returns non-zero if char is a punctuation character (other than the space character), and 0 otherwise. issymbol O is punctuation O is special characters ()Identify errors if there are any & after identifying rewrite the code.

Look at the examples below to get an idea of what the function should do. Examples sumArray ([1, 2, 3, 4, 5]) - 15 sumArray ([-1, 0, 1]) → 0 sumArray ([0, 4, 8, 12]) → 24 Notes READ EVERY WORD CAREFULLY, CHARACTER BY CHARACTER! • Don't overthink this challenge; it's not supposed to be hard.You are writing an application that uses the sqrt function. The program must reference the function using the name squareRoot.You need to import the function.Which code segment should you use? Group of answer choices D. from math.sqrt as squareRoot A. import math.sqrt as squareRoot B. import sqrt from math as squareRoot C. from math import sqrt as squareRoot
- The following function has errors. Locate as many errors as you can. void area(int length = 30, int width) { return length * width; }A spoonerism is when the first letters / sounds of two words are transposed onto one another. Create a function that takes a two-word string and performs a spoonerism on the phrase. Examples spoonerise ("history lecture") "listory hecture" spoonerise("loud noises") → "noud loises" spoonerise("chow mein") → "mow chein" spoonerise ("edabit rules!") Notes → "redabit ules!" • Only two words will be parsed into the function. Don't worry about handling more than two. • You won't always just have to swap the first letters, take care to notice which letters have been switched in the examples (notice the difference between vowel-starting and consonant-starting words).get_column_choice(): this function will allow us to ask the players which pocket they want to grab stones from. Since we know which row they are grabbing from (since it is not allowed to grab stones from your opponent’s side), we only need to get the column they want. As previously stated, we are using letters to represent the columns to make it easier on the player. This function accepts the current player (should be a 0 or 1), the board, and a list of letters (the same as the list you passed to the print_game_board function) and it will return the index of the column being chosen. The function should ask the player to enter a column letter, then it should check that the conditions listed below hold. If they don’t meet these conditions, it should ask again until it gets a valid letter, otherwise it should return the corresponding column index for that letter. Letter entered must be on the game board. It can be lower case or upper case. (Hint: this doesn’t need to be hard coded,…
