Requirements:
- Plan each
program by writing pseudocode. - Add more comments as needed in each program to explain what your code is doing.
- Choose descriptive variable names in all programs.
- Currency format. Use f-strings to generate currency outputs.
Python Question 5a:
program5_1.py
This file is about rectangles. It requires a main function and three custom functions, all of which take the rectangle dimensions as arguments.
- a function that returns the area of a rectangle.
- a void function that prints the perimeter of a rectangle.
- a function that returns the length of a rectangle's diagonal. This function must use a method of the math module.
The main function should prompt the user for the rectangle dimensions (as floats) and execute the custom functions. All calculations should be printed accurate to three decimal places using f-strings.
Sample Output
(See sample_image1.png)
Python Question 5b:
program5_2.py
This program should import program5_1 as a module. Start by making a copy of program5_1.py. Then delete the three custom functions and adjust the code to demonstrate that you understand how the dunders work in Python.
Transcribed Image Text:**Rectangle Properties Calculation**
1. **Input Data:**
- Enter rectangle side 1: 15.0
- Enter rectangle side 2: 8.0
2. **Calculated Results:**
- The area of the rectangle is 120.000 square units.
- The perimeter of the rectangle is 46.000 units.
- The length of the rectangle's diagonal is 17.000 units.
**Explanation:**
- **Area Calculation:**
The area of a rectangle is calculated by multiplying its length and width. In this case, \(15.0 \times 8.0 = 120.0\).
- **Perimeter Calculation:**
The perimeter is calculated by adding the lengths of all sides. The formula is \(2 \times (\text{side 1} + \text{side 2})\). Here, \(2 \times (15.0 + 8.0) = 46.0\).
- **Diagonal Calculation:**
The diagonal can be found using the Pythagorean theorem: \(\sqrt{\text{side 1}^2 + \text{side 2}^2}\). For this rectangle, \(\sqrt{15.0^2 + 8.0^2} = 17.0\).

In this exercise you will create a program that will be used in a digital library to format and sort journal entries based on the authors last name. Each entry has room to store only the last name of the author. Begin by removing the first name "Isaac" from the string variable journal_entry_1 by using the string function erase. Do not forget to also remove the whitespace so that the string variable journal_entry_1 will then contain the string "Newton" with no whitespaces. The journal entries should be sorted alphabetically based on the authors last name. For example, the last name "Brown" should come before the last name "Davis" Create an if statement so that if the last name contained within journal_entry_2 is alphabetically less than the last name contained within journal_entry_1, then the string values are swapped using the string function swap. You may use either of the comparison operators < > in the if statement but remember that following ASCII, "A" is…arrow_forward
