There are three versions of this project.
Version 1 (all interactive). Write a
The output should correctly label the months.
There are a variety of ways to deal with the month names. One straightforward method is to code the months as integers and then do a conversion before doing the output. A large switch statement is acceptable in an output function. The month input can be handled in any manner you wish, as long as it is relatively easy and pleasant for the user.
After you have completed this program, produce an enhanced version that also outputs a graph showing the average rainfall and the actual rainfall for each of the previous 12 months. The graph should be similar to the one shown in Display 7.8, except that there should be two bar graphs for each month and they should be labeled as the average rainfall and the rainfall for the most recent month. Your program should ask the user whether she or he wants to see the table or the bar graph and then should display whichever format is requested. Include a loop that allows the user to see either format as often as the user wishes until the user requests that the program end.
Version 2 (combines interactive and file output). For a more elaborate version, also allow the user to request that the table and graph be output to a file. The file name is entered by the user. This program does everything that the Version 1 program does but has this added feature. To read a file name, you must use material presented in the optional section of Chapter 5 entitled “File Names as Input.”
Version 3 (all I/O with files). This version is like Version 1 except that input is taken from a file and the output is sent to a file. Since there is no user to interact with, there is no loop to allow repeating the display; both the table and the graph are output to the same file. If this is a class assignment, ask your instructor for instructions on what file names to use.

Define and use a new function, isEven, that returns a Boolean to make the condition in the if statement easier to understand. ef main() : page = int(input("Enter page number: ")) if page % 2 == 0 : print(page) else : print("%60d" % page) main()arrow_forwardWhat is the correct python code for the function def countWords(string) that will return a count of all the words in the string string of workds that are separated by spaces.arrow_forward
- Consider the following program that counts the number of spaces in a user-supplied string. Modify the program to define and use a function, countSpaces, instead. def main() : userInput = input("Enter a string: ") spaces = 0 for char in userInput : if char == " " : spaces = spaces + 1 print(spaces) main()arrow_forwardWhat is the python code for the function def readFloat(prompt) 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("Please enter your salary:") percentageRaise = readFloat("What percentage raise would you like?")arrow_forwardassume python does not define count method that can be applied to a string to determine the number of occurances of a character within a string. Implement the function numChars that takes a string and a character as arguments and determined and returns how many occurances of the given character occur withing the given stringarrow_forward
- Consider the ER diagram of online sales system above. Based on the diagram answer the questions below, a) Based on the ER Diagram, determine the Foreign Key in the Product Table. Just mention the name of the attribute that could be the Foreign Key. b) Mention the relationship between the Order and Customer Entities. You can use the following: 1:1, 1:M, M:1, 0:1, 1:0, M:0, 0:M c) Is there a direct relationship that exists between Store and Customer entities? Answer Yes/No? d) Which of the 4 Entities mention in the diagram can have a recursive relationship? e) If a new entity Order_Details is introduced, will it be a strong entity or weak entity?
