Question

Write the code in Python. The output should be exact the same as the given.

Question 1. Study the examples below carefully and write a program for journal subscription Your program should work exactly as the following examples The text in bold indicates user input. Example 1: The user is a student, and the user subscribes to 2 journals Question 1 - Journal of Commodity Markets Journal of Sustainable Mining Journal of Asia-Pacific Biodiversity Student $21 $22 $27 Non-student $50 $60 $75 Are you a student? (Y/N): Y Subscribe to Journal of Commodity Markets? (Y/N): Y Subscribe to Journal of Sustainable Mining? (Y/N): N Subscribe to Journal of Asia-Pacific Biodiversity? (Y/N):Y Your selection: - Journal of Commodity Markets - Journal of Asia-Pacific Biodiversity Total cost $48 Example 2: The user is not a student, and the user subscribes to 1 journal Question 1: - Journal of Commodity Markets Journal of Sustainable Mining Journal of Asia-Pacific Biodiversity Student $21 $22 $27 Non-student $50 $60 $75 Are you a student? (Y/N):N Important requirements: . On the top, the program must use string format to display the journal price. The 1st column must have left alignment with 40 spaces; the 2nd and 3rd columns must have right alignment with 15 spaces. . The program must display all the journals that the user has selected. When the user selects no journals then the program must display "None" as in the Example 3 above The total cost must be calculated correctly depending on the user is a student or non-student. For user input, we assume that the user always enter Y or N, and your program does not have to handle invalid input. Question 3. Study the examples below carefully and write a program to ask the user to enter the length of the square and then display the square. Your program must use for loop statement. Your program should work exactly as the following examples. The text in bold indicates user input. Example 1: The user chooses the square length to be l -Question 3: - Enter the length of square: 1 Here is a square of length 1 Example 2: The user chooses the square length to be 2 --Question 3: -- Enter the length of square: 2 Here is a square of length 2 Example 3: The user chooses the square length to be 3 -Question 3: -- Enter the length of square: 3 Here is a square of length 3 Example 4: The user chooses the square length to be 4 -Question 3: - Enter the length of square: 4 Here is a square of length 4 Example 5: The user chooses the square length to be 5 -Question 3: - Enter the length of square: 5 Here is a square of length 5 ㄊㄊㄊㄊㄊ Objectives Able to write clear code with comments and follow coding convention Able to use variables Able to use string format Able to get user input and display output Able to translate number into string and string into number Able to use if-else statements Able to use loop statements . *
