) Perform error checking for the data point entries. If any of the following errors occurs, output the appropriate error message

emmainna [20.7K]

Answer:

In Python:

entry = input("Sentence: ")

while True:

if entry.count(",") == 0:

print("Error: No comma in string")

entry = input("Sentence: ")

elif entry.count(",") > 1:

print("Error: Too many comma in input")

entry = input("Sentence: ")

else:

ind = entry.index(',')+1

if entry[ind].isnumeric() == False:

print("Comma not followed by an integer")

entry = input("Sentence: ")

else:

break

print("Valid Input")

Explanation:

This prompts the user for a sentence

entry = input("Sentence: ")

The following loop is repeated until the user enters a valid entry

while True:

This is executed if the number of commas is 0

if entry.count(",") == 0:

print("Error: No comma in string")

entry = input("Sentence: ")

This is executed if the number of commas is more than 1

elif entry.count(",") > 1:

print("Error: Too many comma in input")

entry = input("Sentence: ")

This is executed if the number of commas is 1

else:

This calculates the next index after the comma

ind = entry.index(',')+1

This checks if the character after the comma is a number

if entry[ind].isnumeric() == False:

If it is not a number, the print statement is executed

print("Comma not followed by an integer")

entry = input("Sentence: ")

If otherwise, the loop is exited

else:

break

This prints valid input, when the user enters a valid string

print("Valid Input")

Note that: entry = input("Sentence: ") is used to get input

Convert the decimal number 164 into the equivalent 8 bit binary number.

umka2103 [35]

Answer:

10100100

Explanation:

8 bit system consists of 8 bits or 8 positions and each of them can have binary value (0 or 1).

Each bit is equivalent to a certain power of number 2. Important to know is that you read these bits from right to left.

So, this means that the bit furthest to the right has the value of 2^0, which is 1. The bit to the left has the value of 2^1, which is 2. Next one is 2^2, which is 4 etc. This means that the bit furthest to the left has the value of 2^7, which is 128.

The bit has this potential value only if value 1 if is in its position. If the value is 0 then, regardless of position, value of the bit is 0.

Decimal value of the number is calculated when we add all the values of the bits marked with 1.

So, we're dealing with number 164. We already said that leftmost bit has the value of 128 if it's marked with 1:

1 0 0 0 0 0 0 0 = 128

Next bit has the value of 64, but 128+64 would exceed the value of our number, so the second leftmost bit remains 0.

Next bit has the value of 32, 128+32 is 160, which is less then our number, so we mark the third bit with 1:

1 0 1 0 0 0 0 0 = 160

Similarly, we continue down the line. We only need 4 to reach the value of our number, so we'll mark with 1 the bit that has the value of 4, which leaves us with the solution:

1 0 1 0 0 1 0 0 = 164

A weak fuel to air mixture along with normal airflow through a turbine engine may result in?

Sladkaya [172]

Answer:

A weak fuel to air mixture along with normal airflow through a turbine engine may result in a lean die out.

Explanation:

Lean die out is a type of problem that may occur in the turbine. This may result in the weak fuel to air mixture. In case if the mixture of fuel and air is getting low due to some reasons like leakage of gas or low speed of engine may result in dangerous conditions such as fire or blast in the turbine. This is called lean die out. In the result of this problem, the turbine can be burn with the blast and may leads to causalities.
