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.

What is the return value of a function that doesn't specify a return statement or simply has an empty return statement? Example: def x(a,b): print(x) return

Python (this is not graded this is practice work that is not graded) write and test a function which takes two dates (month, day) list arguments.When the function is called with the two arguments, it returns the number of days betweenthose two dates. Print the returned value. It is assumed that the first date occurs first. Forinstance, if the users calls the function with FUNCTION([12, 10], [12, 20]) as arguments, thereturned value is 10 days. However, if FUNCTION([12, 20], [12, 10]) is called, the returnedvalue is -10 days.Assume February has 28 days.Test data: [10, 30], [5, 20] [1, 30], [5, 25] [5, 25], [1, 30] [1, 1], [12, 31]
Problem 2: Write a function called digitMatch. The function has three integer parameters first , second and third that are positive and have the same number of digits. It returns the number of positions where their digits match. For example, if the function was applied to 17345, 97813 and 17313 it would return 1 because only the 2nd digits match. If parameters have illegal values your function can operate however you choose. For example, a program that uses the function follows. int main() { cout <« digitMatch(168, 567, 767) « endl; // prints 1 cout <« digitMatch(143, 243, 343) « endl; // prints 2 return 0; }
