Program 18: Write a program to accept the values of principal, rate, and time and calculate the simple interest.

Ans. def simpleInterest(principal,rate,time):

'''
Objective : To calculate simple interest
Input Parameters :
principal- numeric value denoting principal amount
rate - numeric value denoting rate of interest in % per annum
time - numeric values indicating time period in years

Return Value : None
'''
rate /= 100
simple_interest = principal * rate * time

print(f"Simple Interest: {simple_interest:.2f}")

principal = float(input("Enter the principal amount (P): "))
rate = float(input("Enter the rate of interest (R) as a percentage: "))
time = float(input("Enter the time period (T) in years: "))
simpleInterest(principal,rate,time)

Program 19: Write a function inchesToFeet that accepts the length in inches and returns the length in feet. Invoke
inchesToFeet to compute the length in feet for the length in inches entered by the user.

Ans. def inchesToFeet(lengthInches):
'''
Objective : To calculate feet from inches

Input Parameter : lengthInches - numeric value
Return Value : None
'''
lengthFeet = lengthInches / 12.0
return lengthFeet

lengthInches = float(input("Enter length in inches: "))
lengthFeet = inchesToFeet(lengthInches)
print(f"Length in feet is: {lengthFeet} feet")
Program 20: Write a function that takes the size of memory in bits as input parameter and displays the memory in bytes
and nibbles. The value of memory in bits should be accepted from the user and then passed as an input parameter to the
function. Invoke the function to print the size of memory in bytes and nibbles for the user-inputted memory size in bits.

Ans. def convertMemory(sizeInBits):

'''
Objective : To calculate memory in bytes and nibbles
Input Parameter : sizeInBits – numeric value
