Use Python You are planning to add bookcases to a wall in your living room, but you don't know how many bookcases to buy. You decide to write a Python function, get_num_bookcases, to help. Your function needs to do the following: Take parameters for the width of the wall (an integer number of feet) and the width of a bookcase (an integer number of inches). (Your function does not read input from the keyboard; it gets its input through named parameters.) Calculate how many whole bookcases will fit on the wall using modular arithmetic (use div and/or mod, represented by the operators // and %, as needed to solve the problem). Return the number of bookcases. For example: Test Result print(get_num_bookcases(20, 50)) 4 print(get_num_bookcases(8, 15)) 6 print(get_num_bookcases(3, 40)) 0
There is only 1 ques with 2 part. Please answer the questions ( Answer in python ) Part I: Cities. Write a function called describe_city which accepts the name of a city and its country. The function should print a simple sentence as shown in the output example. Give the parameter for the country a default value. Make 5 calls to the function using the following arguments: Reykjavik, Iceland Pittsburg Ontario, Canada Cairo, Egypt Miami, USA Output Example : ( FOLLOW THE OUTPUT SAME AS GIVEN BELOW ) Reykjavik is in Iceland Pittsburg is in USA Ontario is in Canada Cairo is in Egypt Miami is in USA Part II: Blastoff!!! Write a function called count_down which has 1 integer parameter. The function should countdown from that parameter value to 1. Each step in the countdown should be printed on the same line followed by ‘Blastoff!!!’ also on the same line. All of this should happen in the function. Make 3 calls to the function with the following arguments: 3 5 10 Output…
im having some trouble with this Requirements: Write a Python script that prompts the user for the length of a side of a polygon and prints a table of areas of several polygons. Sample output is shown below. Additional requirements: • Your program should use functions to organize the code. Implement these functions: - main The main function should call the function get_side_length and then send side_length to report. - get_side_length This function should prompt the user ("Input the length of a side: ") and return side_length to main as an int. - report This function should print a heading line ("side length...number of sides...area") and use a loop to print a table of values as shown in the sample output below. The report function should call polygon_area to calculate the areas needed for the table. The function report will have to call polygon_area once for each area that it needs to print. - polygon_area This function takes num_sides and side_length as parameters and returns the…

In Python code: Write a function to convert a integer to hexidecimal. Do not use the Python hex function (i.e. hexnumber = hex(number)) to convert the number, instead write your own unique version (i.e. MYHEX: hexnumber = MYHEX(number)). Your function should not use any Python functions like hex, dec, oct, bin or any other Python functions or modules. Functions, like Python ORD, can be used to convert a string to a integer.
Please help me to solve this. Kindly show all codes with proper indentation. I will be glad if you can test the codes to make sure it works proberly. Thanks a lot for the help. Write a python function called_books() that lists my favorite books regardless of the number of books I give the function.

The binomial coefficient (n, k) is an integer equal to (n, k) = n! / [k! (n – k)!] Note that n! = n(n – 1)(n – 2) … (1) and that 0! = 1. a) Using this form for the binomial coefficient, write a Python user-defined function binomial(n,k) that calculates the binomial coefficient for given n and k. Make sure your function returns the answer in the form of an integer (not a float) and gives the correct value of 1 for the case where k = 0. Use phyton code to answer,
In Python Define stubs for the functions get_user_num() and compute_avg(). Each stub should print "FIXME: Finish function_name()" followed by a newline, and should return -1.

Q2: In this question, you will write a Python function to compute the Hadamard product of two matrices. The Hadamard product is the "component-wise" product of two matrices. That is, each entry of the product matrix is equal to the product of its corresponding entries of the input matrices. Here is an example: a11 a12 a21 a22 a23 a31 a13 SH a32 033 A b11 b12 b13 b21 b22 b23 b31 b32 b33. B = [an bu a21 b21 a31 b31 a12 b12 a22 b22 a32 b32 a13 b13 a23 b23 a33 b33. Hadamard product of A and B Write a Python function to compute the Hadamard product of two matrices as follows. a) The inputs to the function are two matrices. b) The function should check whether the two matrices have the same size. If not, it should print "The input matrices are not of the same size". c) If two matrices are of the same size, the function computes the Hadamard product and returns the answer. Use for loops to compute the Hadamard product.
