Homework Answers

The coordinates of different persons are given in the following dictionary.

position = ('A': (2, 5), 'B': (1, 7), 'C': (9, 5), 'D': (2, 6))

You will take 2 inputs for person X's location where the first

input specifies person X's current location in the x-axis and the second input specifies person X's current location in the y-axis.

Your work is to find the person closest to person X by

calculating the

distance between person X and every other person in the dictionary.

Hint: The distance between two coordinates is given by the

formula (You

need to import math):

math.sqrt((x2-x1)**2 + (y2-y1)**2)

Sample Input 1:

Enter person X's x coordinate: 3

Enter person X's y coordinate: 6

Sample Output 1:

D

Write a Python program that takes a string as an input where multiple numbers are separated by hashes(#). Your first task is to create a list of numbers and print it.

Your second task is to create a dictionary that will have the index of the

list as key, and for the even indices, multiplication from start to that index as value, while for the odd indices, summation from start to that

index as value. Finally, print the dictionary.

Sample Input 1:

1#2#3#4

Sample Output 1:

[1, 2, 3, 4]

(0:1, 1:3, 2:6, 3:10}

Sample Input 2:

5#6#7

Sample Output 2:

[5, 6, 7]

{0: 5, 1:11, 2: 210}

Write a Python program that reads a number and finds the sum of the series

of 1 + 33 + 111 + 3333 +....+N terms. Then it puts the reverse digit of the sum to a list and prints it. [Cannot use built-in reverse() or reversed()]

Sample Input 1:

5

Sample Output 1:

Sum of series: 14589 Reverse sum of series in list: [9, 8, 5, 4, 1]
