If all rules are satisfied, then the functionshould return True.Note that the card number is not actually a number, but is a string of characters. InPython, you can generally use a string the same way you would use a list, e.g.accessing individual characters using their 0-based index. Hint: You will need to do thisfor checking all the rules.However, when you access a character using its 0-based index, Python will treat it as acharacter/letter and not a number, even if it's a digit, and you need to be careful abouthow you use it in mathematical operations. For instance, if you had the characters '1'and '2' and try to add them, Python would concatenate them and use them to form alonger string; in this case, you would get "12". However, if you try to subtract, multiply,divide, etc. then Python will give you an error.To convert a character/letter to a number, use the "int" function, e.g. "x = int('1')" willconvert the character/letter '1' to the number 1 so that you can use it in mathematicaloperations. Hint: you will need this for rules 2-4. DescriptionCredit card companies and banks use built-in security measures when creating theaccount numbers on credit cards to make sure the card numbers follow certain rules(you didn't think they were random, did you?). This means that there are only certainvalid credit card numbers, and validity can quickly be detected by using an algorithmthat may involve adding up parts of the numbers or performing other checks.In this activity, you will implement a function that determines whether or not a cardnumber is valid, according to some simple algorithms. Note that these algorithms arepurely made-up; don't try to use them to create fake credit card numbers! :-)We will assume that the credit card number is a string consisting of 14 characters and isin the format #### #### ####, including the dashes, where '#' represents a digitbetween 0-9, so that there are 12 digits overall. We will revisit this assumption in the anoptional later activity.In the space below, implement a function called "verify" that takes a single parametercalled "number" and then checks the following rules:1. The first digit must be a 4.2. The fourth digit must be one greater than the fifth digit; keep in mind that theseare separated by a dash since the format is ####-####-3. The sum of all digits must be evenly divisible by 4.4. If you treat the first two digits as a two-digit number, and the seventh and eighthdigits as a two-digit number, their sum must be 100.

2. Printing binary Write a function void printBin(int value) that will print an integer as a binary number. Hint: You want to print a 1 or a O based on the high order bit, then you need to move the next to high order bit into the high order bit. You will need to explicitly count the number of bits you have printed. Write a main method that calls printBin multiple times with a few different values to test it. You should try at least a positive number, a negative number and O. Your submission should answer the following questions about this program: • There are at least two approaches to testing the high order bit. Describe one that you did NOT use in your code. • How could you suppress leading zeros in you display? If you did this already, you may just answer that you did.

You are awesome! Could you do these too please? Q4: Create a function that multiply's two numbers together and outputs the answer. The function must accept 2 parameters. Don't forget about SCOPE if you're using varibles inside of your function. Q5: Using your multiply function, use the shortest amount of code to display the following output on the screen: 1 * 1 = 1 2 * 2 = 4 3 * 3 = 9 4 * 4 = 16 5 * 5 = 25 6 * 6 = 36 7 * 7 = 49 8 * 8 = 64 9 * 9 = 81 10 * 10 = 100 Q6: Determine using a conditional statement, if the following variable is a number or is not not a number. If it is not, try to convert it to a number and use your mult() function to multiply it by 2. NOTE: YOU MAY NOT MODIFY ANY VARIBLES that are Constants. const number = "17";

Write a function that takes in the current temperature and a boolean value telling if it is raining and it should return True if Alfonso will wear a jacket and False otherwise. Try solving this problem with a single line of code. def wears_jacket(temp, raining): """ >>> wears_jacket(90, False) False >>> wears_jacket(40, False) True >>> wears_jacket(100, True) True """ *** YOUR CODE HERE *** Note that it should either return True or False based on a single condition, whose truthiness value will also be either True or False. Part 2: Rewrite the above function with a lambda expression.
