If you have a list consisting of just numbers, then you can add all of the values in the list using the sum() function. If your list consists of some numbers and some values of other types (e.g., lists, strings, sets), the sum() function will fail. In this question, we're asking you to write a function that will sum all of the numbers in a list, ignoring the non-numbers. The function below takes one parameter: a list of values (value_list) of various types.


The recommended approach for this:

(1) create a variable to hold the current sum and initialize it to zero,

(2) use a for loop to process each element of the list,

(3) test each element to see if it is an integer or a float, and, if so, add its value to the current sum,

(4) return the sum at the end.

Answer 1
Answer:

Answer:

See explaination

Explanation:

def sum_lengths(value_list):

total = 0

for x in value_list:

if (type(x)==int) or (type(x)==float):

total += x

return total

The program that you create for this exercise will begin by reading the cost of a meal ordered at a restaurant from the user. Then your program will compute the tax and tip for the meal. Use your local tax rate when computing the amount of tax owing. Compute the tip as 18 percent of the meal amount (without the tax). The output from your program should include the tax amount, the tip amount, and the grand total for the meal including both the tax and the tip. Format the output so that all of the values are displayed using two decimal places.

Which of the following statements describes a limitation of using a computer simulation to model a real-world object or system?a. Computer simulations can only be built after the real-world object or system has been created.
b. Computer simulations only run on very powerful computers that are not available to the general public.
c. Computer simulations usually make some simplifying assumptions about the real-world object or system being modeled.

Answers

Answer:

The answer is "Option c".

Explanation:

Computer simulation, use of a machine to simulate a system's vibration signals by another modeled system's behaviors. A simulator employs a computer program to generate a mathematical model or representation of a true system. It usually gives a lot of simplifications concerning the physical image or system that is modeled, so this statement describes the limitation of using a computer simulation in modeling a real-world object or process.

What is a digital projector? How is it different from computer screen?

Answers

Answer:

An LCD projector is a type of video projector for displaying video, images, or computer data on a screen or other flat surface. It is a modern equivalent of the slide projector or overhead projector.

It's different because in a computer display, the screen is the physical surface on which visual information is presented. This surface is usually made of glass.

Explanation:

A digital projector is a device that projects video or images onto a large screen, suitable for shared viewing in larger settings. It differs from a computer screen in terms of size, portability, shared viewing capabilities, image quality, source connectivity, and adjustments.

A digital projector is a device that takes a video or image signal from a computer, DVD player, or other multimedia source and projects it onto a large screen or surface.

The key differences between a digital projector and a computer screen:

Size: The most obvious difference is the size of the display.

Portability: Computer screens are generally fixed and not easily portable, whereas digital projectors are often designed for mobility.

Shared Viewing: A computer screen is designed for individual or small group viewing at close distances, while a digital projector is meant for larger audiences.

Image Quality: Digital projectors vary in imagequality, and high-quality projectors can offer impressive resolution and brightness suitable for movie screenings or professional presentations.

Source Connectivity: Both a computer screen and a digital projector can receive input from computers and other multimedia sources.

Placement and Adjustment: Digital projectors often provide manual or automatic keystone correction and focus adjustments to ensure the projected image remains proportional and clear on the screen or surface.

Hence,  a digital projector is a device used to project large-scale images or video onto a screen or surface, suitable for shared viewing in larger settings.

Answer:

A. Artificial Narrow Intelligence.

Explanation:

Artificial intelligence is the ability of a computer system, with the help of programming, automatically make decisions as humanly as possible, based on the input value received. There are three types of artificial intelligence, namely, artificial narrow intelligence (ANI), artificial general intelligence (AGI) and artificial super intelligence (ASI).

ANI is focus on executing one specific task extremely well like web crawler, speech recognition, email spam filters etc. AGI is meant to handle human intellectual task, while ASI performs task beyond human intellect.
