Write and test the “digit” function:Function Prototype: int digit(int n,int k)This function returns the kth digit of the positive integer n. For example, if n is the integer 29,415, then the call digit(n,0) would return the digit 2, and the call digit(n,2) would return the digit 4.
Write a function called area circumference generator that takes a radius of a circle as a function parameter and calculates its circumference and area. Then returns these two results as a tuple and prints the results using tuple unpacking in the function call accorrding to the given format. [Must use tuple packing & unpacking] Example1: Function Call: area_circumference_generator(1) Output: (3.141592653589793, 6.283185307179586) Area of the circle is 3.141592653589793 and circumference is 6.283185307179586 ======== :===== Example2: Function Call: area_circumference_generator(1.5) Output: (7.0685834705770345, 9.42477796076938) Area of the circle is 7.0685834705770345 and circumference is 9.42477796076938

There is only 1 ques with 2 part.please answer them.( Please answer in python) Part I : Define a function called larger with 2 parameters. The function should compute which is the larger and should subtract the smaller from the larger (regardless of the order of arguments). Call the function four times using the following arguments: (75, 59) (43, 45) (-5, 19) (35, -35) Output Example: 16 2 24 70 Part II Gas Price Averaging a) Write a function average with a parameter prices that can accept an arbitrary number of integer values. This function returns the average of all values. b) Call the average function with the following arguments: 2.95, 3.25, 3.10, 3.19 c) Call the average function with the following arguments: 4.09, 3.89, 3.75 d) Print and format the returned results with the average computed to two decimal places. Match the output below. Output Example Village gas prices at the start of the year averaged $3.12 Village gas prices today average $3.91
1. Square Flower You can have the turtle draw an interesting flower like sha pe by drawing n squares. Each n-square flower is drawn after turning the turtle by some number of degrees between each square. (see Figure 1 for an example) (a) Typel: A 5-square red flower. (b) A 15-square blue flower. Figure 1: Two types of n-square flowers Using the following implementation of draw square() function write a function na med draw flower() that takes a turtle, the number n of squares to draw, the side length and a color as parameters and draws an n-square flower by repeating the function draw square() n times. Test your code by drawing a yellow 21-square flower with side length of 200. def drav aqu ar e (aTurtle, sidelength): f or i in range (4) : aTurtle.forvard (side Length) aTurtle. 1eft (90)
Please write out the code for this function using R.
NOTE: Solve this as soon as possible, I need this urgently. (a). Write a function that takes an integer as input and finds whether it is a prime number or not . Function should return 1 if number is prime , 0 otherwise. In main(), ask the user to enter the number and call the funcltion. Based upon the value returned by the function , main() will display on screen, if the number is prime or not.
(2) The ceiling of a floating-point number x is the smallest integer that is still larger than or equal to x. Alternatively, the ceiling of a floating-point number x is what you get when you round x up to the nearest integer. For example, the ceiling of 2.1 is 3, the ceiling of 0.9 is 1, the ceiling of -4.5 is -4, etc. Write a function called ceiling (number) to compute the ceiling of a floating-point number (input argument) and returns one integer value. You may not use python's ceil() or floor() functions. Your function may use int() and/or float() functions, and your solution must use the floor division operator (i.e., '//").

a. Consider the Boolean expression ((x 100)) Why is this expression probably not what the programmer intended? b. Write a function that will receive a matrix as an input argument and will calculate and return the overall average of all numbers in the matrix. Use loops, not built-in functions, to calculate the average.
Write and test the “digit” function: Function Prototype: int digit(int n,int k)This function returns the kth digit of the positive integer n. For example, if n is the integer 29,415 that is entered by user , then the call digit(n,0) would return the digit 2, and the call digit(n,2) would returnthe digit 4. do this only by using functions and loops. arrays are not allowed. example :Input: n = 29415 , k = 1 output: 9 Input: n = 2 , k = 1 output: index out of bound (return -1)
