Write a Python function LetterGame() that repeatedly asks the user to input a letter. The function is to count the number of vow

kotegsom [21]

Answer:

def LetterGame():

vowels = ["a", "e", "i", "o", "u", "A", "E", "I", "O", "U"]

count1 = count2 = 0

while True:

choice = input("Enter a letter / digit to stop: ")

if choice.isdigit():

break

elif choice.isalpha():

count1 += 1

if choice in vowels:

count2 += 1

print("You entered " + str(count1) + " letters, " + str(count2) + " of which weere vowels.")

print("The percentage of vowels was " + str(count2 / count1 * 100) + "%")

LetterGame()

Explanation:

Create a function called LetterGame

Inside the function:

Create a list of vowels

Initialize count1, counts the total letters, and count2, counts the vowels

Initialize a while loop that iterates until the specified condition is met in the loop

Get the input from the user. If it is a digit, stop the loop. If it is an alphabet, increase the count1 by 1, and also check if it is a vowel. If it is a vowel, increment the count2 by 1

When the loop is done, print the required information

Finally, call the function

A circuit contains three resistors connected in parallel. The value of R1 is 2 K , the value or R2 is 6 K , and the value of R3

mezya [45]

In a parallel connection, the voltage is same in every branch.
Now, three <span>three resistors connected in parallel.
R1 = 2k ohm
</span>R2 = 6k ohm
R3 = 10k ohm
in parallel, net resisitance = $\frac{ R_{1}R_{2}R_{3} }{R_{1}R_{2} + R_{2}R_{3} + R_{3}R_{1}}$

Now, putting the values, we get, R net = 1.30 k ohm.
Ans, voltage = 100 VDC
Thus, power = $\frac{ V^{2} }{R} = \frac{ 100^{2} }{1.3 k} \\ \\ where \\ k = 10^{3}$
= 7.69 Watt
