Write a program that will ask the user for a set of ten numbers. After all ten numbers have been entered, the program will displ

muminat

Answer:

In Python:

nums = []

larg= []

small = []

while True:

for i in range(10):

num = int(input(": "))

nums.append(num)

print("Smallest: "+str(min(nums))); print("Largest: "+str(max(nums)))

larg.append(max(nums))

small.append(min(nums))

another = int(input("Press 1 to for another sets: "))

nums.clear()

if not another == 1:

break

print("Average Large: "+str(sum(larg)/len(larg)))

print("Average Small: "+str(sum(small)/len(small)))

Explanation:

This initializes the list of input numbers

nums = []

This initializes the list of largest number of each input set

larg= []

This initializes the list of smallest number of each input set

small = []

This loop is repeated until, it is exited by the user

while True:

The following iteration is repeated 10 times

for i in range(10):

Prompt the user for input

num = int(input(": "))

Add input to list

nums.append(num)

Check and print the smallest using min; Check and print the largest using max;

print("Smallest: "+str(min(nums))); print("Largest: "+str(max(nums)))

Append the largest to larg list

larg.append(max(nums))

Append the smallest to small list

small.append(min(nums))

Prompt the user to enter another set of inputs

another = int(input("Press 1 to for another sets: "))

Clear the input list

nums.clear()

If user inputs anything other than 1, the loop is exited

if not another == 1:

break

Calculate and print the average of the set of large numbers using sum and len

print("Average Large: "+str(sum(larg)/len(larg)))

Calculate and print the average of the set of smallest numbers using sum and len

print("Average Small: "+str(sum(small)/len(small)))

nadezda [96]

Answer:

def course_grader(student_to_grades, course_prefix):

student_grades = dict()

for key, value in student_to_grades.items():

grade_score = 0

for course,grade in value.items():

if course_prefix == course:

grade_score += grade

student_grades[key] = grade_score / len(value.keys())

return student_grades

Explanation:

The course_grader function is a python program that accepts two arguments, the student dictionary and the course prefix. The function returns a dictionary of the student id as the key and the average grade of the student as the value.

Explain the need for data structures when developing software.

Sergio [31]

Solution:

It is important because, it has to do operation on so without, data structures and algorithms.

It performs these operation:

1)Take an input

2) Process it

3) Give back the output.

The input can be in any form, for ex while searching for directions on google maps, the starting point and the destination as input to google maps, while logging in to any social sites, We have to give our email and password as input and so on.

Similarly, in the third step, the computer application gives us output in some form or the other.

To make this process efficient, we need to optimize all the three steps.

Primary U.S. interstate highways are numbered 1-99. Odd numbers (like the 5 or 95) go north/south, and evens (like the 10 or 90)

yanalaym [24]

Answer:

The solution in python.

Output:

print("0 is not a valid interstate highway number")

Explanation:

h = int(input("enter highway number: ")) #take highway number

if(h>=1 and h<=99): #for primary highway

if(h%2==0):

print("I-%d is primary, going east/west" %h) #for even highway number

else:

print("I-%d is primary, going north/south" %h) #for odd highway number

elif(h>=100 and h<=999): #for auxiliary highway

aux=str(h) #convert into string for fetch the rightmost number

l=len(aux) #find the length

val = aux[l-2]+aux[l-1] #assign value of rightmost two number

h = int(val) #convert into integer

if(h%2==0):

print("I-"+aux+" is auxiliary,"+"serving I-%d, going east/west" %h)

else:

print("I-"+aux+" is auxiliary,"+"serving I-%d, going north/south" %h)

elif(h==0):#for 0 highway number

print("0 is not a valid interstate highway number")

else:

pass
