Question

b) Assume that someone has collected a set of measurements and wants some statistical data about them. Write a program that asks a user for measurements and prints the average, the maximum, and minimum measurement. User should be allowed to enter as many measurements as they want, until entering a negative measurement. The negative measurement should not be processed, but is just used to indicate that the user has finished entering measurements. (Do not use a list to store the measurements) (Working in Python 3.7 (Spyder))

c) For numbers from 2 to 100 print a series of lines indicating which numbers are divisors of other numbers. For each, print out "X divides Y", where X<=Y, and both X and Y are between 2 and 100. First few lines will be 2 divides 2, 3 divides 3...etc (Working in Python 3.7)

Answer 1

Here is the completed code for this problem. Comments are included, go through it, learn how things work and let me know if you have any doubts or if you need anything to change. If you are satisfied with the solution, please rate the answer. Thanks

Note: If second part is not what you are looking for. Just let me know.

#code for first part

#initializing total, count to 0

total=0

count=0

#initializing max and min to None

max=None

min=None

n=0

#looping until n is not negative

while n>=0:

    #getting input

    n=float(input('Enter a measurement (or a negative value to quit): '))

    #checking if n is 0 or positive

    if n>=0:

        #adding to total, updating count

        total+=n

        count+=1

        #updating max if n is greater than max or max's value is not initialized yet

        if max==None or n>max:

            max=n

        # updating min if n is less than min or min's value is not initialized yet

        if min==None or n<min:

            min=n

#finding average if count is above 0

avg=0

if count>0:

    avg=total/count

#displaying average, max and min

print('Average value: ',avg)

print('Maximum: ',max)

print('Minimum: ',min)

#code for second part

#looping from i=2 to i=100

for i in range(2,100+1):

    #looping from j=i to j=100

    for j in range(i,100+1):

        #checking if i divides j evenly

        if j%i==0:

            #displaying i and j

            print('{} divides {}'.format(i,j))

#output 1
