GPT-4 User write some short unreadable spaghetti code and then rewrite it organized around its intended interface ChatGPT ### Unreadable Spaghetti Code: ```python def z(a,b):return a+b;c=10;d=5;print(z(c,d));def y(x):return x*2;e=z(c,d);f=y(e);print(f);def w(v,u):return v-u;print(w(f,e)) ``` This code sums, multiplies, and subtracts numbers but is difficult to follow due to the lack of structure and clear naming. The code does the following: - Defines a function `z` that adds two numbers, but then executes other code before utilizing it. - Defines variables `c` and `d`, then prints their sum using `z`. - Defines another function `y`, multiplies the previous sum by 2, and prints it. - Defines a function `w` to subtract two numbers, then immediately calculates and prints a new result. ### Organized Code: Here’s the code refactored to be readable and structured: ```python def add(a, b): return a + b def multiply(x, factor=2): return x * factor def subtract(v, u): return v - u def main(): # Setting initial values c, d = 10, 5 # Performing calculations sum_result = add(c, d) double_sum = multiply(sum_result) final_result = subtract(double_sum, sum_result) # Displaying results print("Sum:", sum_result) print("Doubled Sum:", double_sum) print("Subtracted Value:", final_result) if __name__ == "__main__": main() ``` **Explanation:** 1. **Separate Functions**: Each mathematical operation is performed by a separate function with a clear name (`add`, `multiply`, `subtract`). 2. **Named Variables**: Variables have descriptive names to clarify their purpose (`sum_result`, `double_sum`, `final_result`). 3. **Main Function**: A `main()` function contains the primary logic to ensure readability and reusability. 4. **Print Statements**: Each result is printed with a label to understand the output. 5. **Conditional Execution**: `if __name__ == "__main__":` ensures that `main()` runs only when the script is executed directly, not when imported as a module. This way, the organized code makes it easier to understand the functionality, modify it, and use it in other programs.
