A state where all data integrity constraints are satisfied is called a consistent state. It is achieved by ensuring that any data which are going to be written follow the database rules. <span>If a certain attempt to introduce inconsistent data occurs, the attempt is rolled back and an error will be returned to the user.</span>

Taya2010 [7]

Answer:

num1 = float(input("Enter the first number: "))

while True:

   print("Add, Subtract, Multiply, Divide, or Quit ?")

   choice = input("Your choice is: ")

   if choice == "Quit":

       break

   num2 = float(input("Enter the second number: "))

   if choice == "Add":

       num1 += + num2

       print("The subtotal is: " + str(num1))

   elif choice == "Subtract":

       num1 -= num2

       print("The subtotal is: " + str(num1))

   elif choice == "Multiply":

       num1 *= num2

       print("The subtotal is: " + str(num1))

   elif choice == "Divide":

       num1 /= num2

       print("The subtotal is: " + str(num1))

print("The final result is: " + str(num1))

Explanation:

Ask the user for the first number

Create a while loop that iterates until specified condition occurs inside the loop

Ask the user for the operation or quitting

If the user chooses quitting, stop the loop. Otherwise, get the second number, perform the operation and print the subtotal

When the loop is done, the user enters Quit, print the final value result

If your TV was showing a flat black or blue screen, or had "snow", what steps would you take to fix it?
faust18 [17]

Answer:

Assuming that TV was working fine and it stopped working when you restart or after power shutdown. Flat Black or blue screen or snow are all seems to be having HDMI cable sync issues. It can be fixed based on the model of the TV and connectivity it is using.

I would suggest to start with very basic step and should go step by step unless we narrow down the problem.

  1. Turn off all the components, unplug the cables and plug them back by leaving HDMI cables intact. So this process will reset all the units and may help in renegotiation.
  2. Plug all the cables and Turn on the TV.  Plug all other components like sound receiver and source device and Turn on the power.  This may solve the problem.
  3. If issue still persist. Unplug and Plug back HDMI cables and surrounding components in HDMI path. It may solve the issue.
  4. If the issue still persists, then change the HDMI cable itself and try rebooting all components.
  5. If input is changed then it might have caused the issue. So identify the cable from the receiver to the TV.  figure out its input and change the TV input to that value and it will work.
  6. In some TV's if power reset happens, It may revert to TV mode then change the video input based on your TV model.
  7. If the receiver is connected to TV via Coax then change the channel as per TV guide.
  8. If the receiver and its component is using AV or HDMI then use TV remote to change the input source until correct feed is found.
  9. If issue still persist, check the cable with another TV and see if it works. If its not then cable is at fault.
  10. If the cable is fine then change the TV and try above steps.If it works then TV is at fault.
