Problem 1
Write the following functions and provide a program to test them. a. def smallest(x, \(\left.y_{,}, 2\right)\) (returning the smallest of the arguments) b. def average \((x, y, z)\) (returning the average of the arguments)
Problem 2
Write function headers with comments for the tasks described below. a. Computing the larger of two integers b. Computing the smallest of three floating point numbers c. Checking whether an integer is a prime number, returning True if it is and False otherwise d. Checking whether a string is contained inside another string e. Computing the balance of an account with a given initial balance, an annual interest rate, and a number of years of carning interest f. Printing the halance of an account with a given initial balance and an annual interest rate over a given number of years 9\. Printing the calendar for a given month and ycar h. Computing the day of the week for a given day, month, and year (as a string such as "Monday") i. Generating a random integer between 1 and \(n\)
Problem 3
'Irue or false? a. A function has exactly one return statement. b. A function has at least one return statement. c. A function has at most one return value. d. A function that does not return a value never has a return statement. e. When executing a return statement, the function exits immediately. f. A function that does not return a value must print a result. 9\. A function without parameter variables always returns the same value.
Problem 3
Write the following functions. a. def firstoigit (n) (returning the first digit of the argument) b. def lastDigit \((\mathrm{n})\) (retuming the last digit of the argument) c. def digits (e) (returning the number of digits of the argument) For example, firstoigit \((1729)\) is 1, 1astDigit \((1729)\) is 9 , and digits \((1729)\) is 4. Provide a program that tests your functions.
Problem 4
Write a function def niddle(string) that returns a string containing the middle character in string if the length of string is odd, or the two middle characters if the length is even. For example, nidde("niddle") returns "dd".
Problem 4
'Irue or false? a. A function has exactly one return statement. b. A function has at least one return statement. c. A function has at most one return value. d. A function that does not return a value never has a return statement. e. When executing a return statement, the function exits immediately. f. A function that does not return a value must print a result. 9\. A function without parameter variables always returns the same value.
Problem 5
Write a function def repeat(string, \(n\), delin) that returns the string string repeated n times, separated by the string delin. For example, repest \(\left(\right.\) "ho \(^{*}, 3,^{\circ}\), ") returns "ho, to, ho".
Problem 5
What is the difference between an argument and a return value? How many arguments can a function call have? How many return values?
Problem 7
Write a function def countwords(string) that returns a count of all words in the string string. Words are separated by spaces. For example, countionds ("yary had a 1ittle lasb") should retum 5.
Problem 10
Write a function def readfloat(proept) that displays the prompt string, followed by a space, reads a floating point number in, and returns it. Here is a typical usage: salary = readfloat("P1tase enter your sa1ary: \({ }^{7}\) )
