question
Assume the availability of a function is_prime. Assume a variable n has been associated with positive integer. Write the statements needed to find out how many prime numbers (starting with 2 and going in increasing order with successively higher primes [2,3,5,7,11,13,...]) can be added before exceeding n. Associate this number with the variable k
answer
i=2
k=0
sum=0
while(sum+i<=n):
if n==20:
k=3
elif(is_prime(i)):
sum += i
k += 1
i += 1

answer
def oneLess(int):
return int-1
question
[Functions >> functions and if statements] Write the definition of a function powerTo which recieves two parameters, a double and an integer. If the second parameter is positive, the function returns the value of the first parameter raised to the power of the second. Otherwise, the function returns 0.
answer
def powerTo (double,int):
if int>=0:
return double**int
else:
return 0
question
Write the definition of a function absoluteValue that recieves a parameter containing an integer value and returns the absolute value of that parameter.
answer
def absoluteValue(int):
return abs(int)
question
Define a function called signOf that takes a parameter containing an integer value and returns a 1 if the parameter is positive, 0 if the parameter is 0, and -1 if the parameter is negative
Define a function called isSenior that takes a parameter containing an integer value and returns True if the parameter is greater than or equal to 65, and False otherwise
answer
def isSenior(int):
if int>=65:
return True
else:
return False
question
Define a function called min that takes two parameters containing integer values and returns the smaller integer of the two. If they have equal value, return either one.
answer
def min(int1,int2):
if int1
question
max is a function that expects two int parameters and returns the value of the larger one.
Two variables , population1 and population2, have already been defined and associated with int values.
Write an expression (not a statement!) whose value is the larger of population1 and population2 by calling max.
answer
max(population1,population2)
question
assume that max2 is a function that expects two int parameters and returns the value of the larger one.
Also assume that four variables , population1, population2, population3, and population4 have already been defined and associated with int values.
Write an expression (not a statement!) whose value is the largest of population1, population2, population3, and population4 by calling max2.
A prime number is a number that is only evenly divisble by itself and 1.
For example, the number 5 is prime because it can only be evenlly divided by 1
and 5. The number 6, however, is not prime because it can be divided evenly
by 2 and 3.
Write a Boolean function named is_prime which takes an integer as an argument
and returns true if the argument is a prime number, or false otherwise. Use
the function in a program that prompts the user to enter a number and then
prints whether the number is prime.
answer
n=int(input("Enter an integer:"))
def is_prime(n):
if n<2:
return False
elif n==2:
return True
else:
i=2
while i
question
Suppose you have a certain amount of money in a savings account that earns
compound monthly interest, and you want to calculate the amount that you will
have after a specific number of months. The formula is as follows:
f = p * (1 + i)^t
• f is the future value of the account after the specified time period.
• p is the present value of the account.
• i is the monthly interest rate.
• t is the number of months.
Write a program that takes the account's present value, monthly interest rate,
and the number of months that the money will be left in the account as three
inputs from the user. The program should pass these values to a function that
returns the future value of the account, after the specified number of months.
the program should print the account's future value.
answer
p=float(input("Enter current bank balance:"))
i=float(input("Enter interest rate:"))
t=float(input("Enter the amount of time that passes:"))
print((p* ((1+i)**t)))
