Answer:
1)
Add this while statement to the code:
while(keep_going!='n'):
#the program keeps asking user to continue bidding until the user enter 'n' to stop.
2)
Here is the code for ACTIVITY 53.3. While loop: Insect growth:
num_insects = int(input())
while num_insects <= 100:
print(num_insects, end=' ')
num_insects = num_insects * 2
Explanation:
Here is the complete code for 1)
import random
random.seed (5)
keep_going='-'
next_bid = 0
while(keep_going!='n'):
next_bid = next_bid + random.randint(1, 10)
print('I\'ll bid $%d!' % (next_bid))
print('continue bidding?', end='')
keep_going = input()
Here the the variable keep_going is initialized to a character dash keep_going='-'
The statement keep_going = input() has an input() function which is used to take input from user and this input value entered by user is stored in keep_going variable. while(keep_going!='n'): is a while loop that keeps iterating until keep_going is not equal to 'n'. print('continue bidding?', end='') statement prints the continue bidding? message on the output screen. For example the user enters 'y' when this message appears on screen. So keep_going = 'y' . So the operation in this statement next_bid = next_bid + random.randint(1, 10) is executed in which next_bid is added to some randomly generated integer within the range of 1 to 10 and print('I\'ll bid $%d!' % (next_bid)) prints the result on the screen. Then the user is prompted again to continue biffing. Lets say user enters 'n' this time. So keep_going = 'n'. Now the while loop breaks when user enters 'n' and the program ends.
2)
num_insects = int(input()) #the user is prompted to input an integer
while num_insects <= 100: #the loop keeps iterating until value of num_insects exceeds 100
print(num_insects, end=' ') #prints the value of num_insects
num_insects = num_insects * 2 #the value of num_insects is doubled
For example user enters 8. So
num_insects = 8
Now the while loop checks if this value is less than or equal to 100. This is true because 8 is less than 100. So the body of while loop executes:
print(num_insects, end=' ') statement prints the value of num_insects
So 8 is printed on the screen.
num_insects = num_insects * 2 statement doubles the value of num_insects So this becomes:
num_insects = 8 * 2
num_insects = 16
Now while loop checks if 16 is less than 100 which is again true so next 16 is printed on the output screen and doubled as:
num_insects = 16 * 2
num_insects = 32
Now while loop checks if 32 is less than 100 which is again true so next 32 is printed on the output screen and doubled as:
num_insects = 32 * 2
num_insects = 64
Now while loop checks if 64 is less than 100 which is again true so next 64 is printed on the output screen and doubled as:
num_insects = 64 * 2
num_insects = 128
Now while loop checks if 128 is less than 100 which is false so the program stops and the output is:
8 16 32 64
The programs along with their output is attached.
Answer:
Explanation:
K- is the working procedure:
It takes n no. of predefined cluster as input and data points.
It also randomly initiate n centers of the clusters.
In this case the initial centers are given.
Steps you can follow
Step 1. Find distance of each data points from each centers.
Step 2. Assign each data point to the cluster with whose center is nearest to this data point.
Step 3. After assigning all data points calculate center of the cluster by taking mean of data points in cluster.
repeat above steps until the center in previous iteration and next iteration become same.
A1(4,8), A2(2, 4), A3(1, 7), B1(5, 4), B2(5,7), B3(6, 6), C1(3, 7), C2(7,8)
Centers are X1=A1, X2=B1, X3=C1
A1 will be assigned to cluster1, B1 will be assigned to cluster2 ,C1 will be assigned to cluster3.
Go through the attachment for the solution.
