Create a function that takes in an integer n and returns the least commonly occurring non-zero decimal digit of n.
never be the least commonly occurring decimal digit if it appears at all in n.
This digit must exist in n, and it is guaranteed that n > 0, in other words, 0 will
If there are multiple digits that are least occurring, return the smallest of such digits.
>>> least_common (123)
1.
>>> least_common (1123)
2.
>>> least_common(12321)

Write a function, called CompoundInterestSchedule, that creates and returns a pandas DataFrame, where each row has: time (in years, an integer starting at 1), starting balance, interest earned, and ending balance, for an investment earning compoundedinterest. Use a for(or while) loop to create this table. The equation for theith year's ending balance is given by: Ei =Bi (1+r/f)f where: Ei is year i's ending balance Bi is year i's beginning balance (note: B1 is the amount of the initial investment (principal) r is the annual rate of interest (in decimal, e.g., 5% is .05) f is the number of times the interest rate compounds (times per year) The interest earned for a given year is Ei - Bi Note the term of the investment (in years) is not in the above equation; it is used…arrow_forwarda Write a function cutF2 that returns its argument with the first two items removed.

- post in python please and a coding editor too You are asked to help write a program that will help users purchase cookies. A user will input types of cookies and the number of cookies that they want, and your program will suggest how many boxes that they should order. There are 30 cookies per box, so your goal is to make sure that the user will buy enough boxes so that they will get the cookies that they want. Write a function cookie_order that takes a dictionary as a parameter containing cookie names as keys and numbers of those cookies as values. Have this function return a new dictionary that has cookie names and the number of boxes that should be purchased of each type. Hint: This means if someone wants 31 cookies, they need to buy 2 boxes of cookies of that type. You may want to consider using math.ceil for this problem. Examples: >>> cookie_order({'thin mints': 97}) {'thin mints': 4} >>> cookie_order({'thin mints':34, 'shortbread': 60, 'caramel delites': 71,…arrow_forwardPython Your class announced a new grade policy: any of your quiz score that are less than 80 will have 2 points added to them.You decide to check whether the proposed grade replacement policy changes your overall quiz grade.
