open Idle And Type Your Program In Idlecalculates The Overall Grade

Open Idle and type your program in Idle. The program should perform the following tasks:

1. Calculate the overall grade for four equally-weighted programming assignments, where assignments 1 and 2 are graded out of 50 points and assignments 3 and 4 are graded out of 75 points. Additionally, calculate the overall grade for a course with three equally-weighted exams (graded out of 100) that account for 60% of the overall grade and four equally-weighted programming assignments (graded out of 50) that account for 40% of the overall grade. Use the formula: overall grade = 0.6 exam average + 0.4 assignment average.
2. Write a program that prompts the user to enter the mass of an object, then calculates its weight using the formula: weight = mass x 9.8. The program should display a message indicating if the object is too heavy (more than 500 N) or too light (less than 100 N). Implement the logic using if-else statements.
3. Create a program that prompts the user to enter a non-negative integer and then calculates the factorial of that number using a loop. After computation, display the factorial value. For example, entering 4 should output 24.

The program should combine all these functionalities, possibly as different functions or sequential sections, and be written clearly following Python best practices.

Paper For Above instruction

The implementation of the described program in Python involves several components, each designed to perform a specific task as outlined. First, the program calculates the overall course grade based on individual assessment scores, then assesses the weight of an object based on user input, and finally, computes the factorial of a provided non-negative integer using a loop.

Calculating the Overall Grade

Accurate calculation of academic grades is essential for students to understand their performance in a course. The program gathers grades for four programming assignments, each with different maximum scores (two out of 50 and two out of 75), then normalizes these scores to a common scale to compute an average. For instance, assignment 1 might have a score of 45/50, which translates to 90%. Summing the normalized scores and dividing by the number of assignments yields the assignment average.

The same approach applies to the exams: the scores for three exams, each out of 100, are averaged. Then, applying a weighted average approach, the overall grade is calculated by multiplying the exam average by 0.6 and the assignment average by 0.4, as per the provided formula. Implementing this requires prompting the user for each score, performing the necessary calculations, and then outputting the final course grade in percentage form. This segment demonstrates proficiency in user input handling, arithmetic operations, and weighted averages in Python.

Object Weight Assessment

The second part of the program prompts the user for the mass of an object and calculates its weight in Newtons using the gravitational acceleration constant (9.8 m/s²). The formula is straightforward: weight = mass * 9.8. Once the weight is computed, the program employs if-else statements to evaluate whether the object is too heavy (weight > 500 N) or too light (weight

Factorial Calculation Using Loop

The final component involves asking the user for a non-negative integer and calculating its factorial value through a loop. The factorial of a number n is the product of all positive integers less than or equal to n, with factorial of 0 defined as 1. The program initiates a variable, say 'factorial', with 1, then iterates from 1 to n, multiplying 'factorial' by the current loop index at each step. After the loop completes, the program displays the resulting factorial. This serves as a practical exercise in looping constructs, iterative multiplication, and validating user input for non-negativity separately.

Integrated Program Design

The overall design of the program can be structured with functions to modularize tasks: one for grade calculation, one for weight determination, and one for factorial computation. The main function calls each of these in sequence or based on user choice, thus creating an interactive and comprehensive program that demonstrates core programming concepts such as input/output, control statements, loops, and arithmetic operations.

Conclusion

Developing this multi-function program not only reinforces fundamental programming skills in Python, such as handling user input, using control flow and loops, and performing calculations, but also illustrates how to integrate different functionalities into a cohesive application. Such exercises are vital in building problem-solving skills critical for computer science and programming careers. By implementing accurate calculations, validating inputs, and providing user-friendly outputs, the program fulfills its educational purpose effectively, offering practical application of core programming principles.
