Question

Python 3

The number of socks of different colors in a drawer full of colored socks is represented as follows: socks = { 'red':4 , 'blue':15, 'white':10, 'black':20, 'brown':11 } a) Draw a simple bar chart to represent this information b) Convert the dictionary into a list containing the color names (as strings) repeated as many times as given in the dictionary. That will look like ['red', 'red', 'red', 'red','blue'....., 'brown']. Do not do this manually. Write a program that will build the list from whatever colors and whatever values are given in the dictionary. c) Randomly select an item (a color name) from this list 1000 times and print the number of times you picked 'black'. (5 + 10 + 5 points)

Answer 1

Code:

import random as r

d = {'red':4,  'blue':15, 'white':10, 'black':20, 'brown':11}
for i in d.keys():
    print(i, ":", end=" ")
    for j in range(d[i]):
        print("*", end = " ")
    print()

# b
colours = list(d.keys())
print(colours)

#c
count = 0

for i in range(1000):
    if r.choice(colours) == 'black':
        count += 1

print('Black picked {} times.'.format(count))

Ouput:

red : * * * *
blue : * * * * * * * * * * * * * * *
white : * * * * * * * * * *
black : * * * * * * * * * * * * * * * * * * * *
brown : * * * * * * * * * * *
['red', 'blue', 'white', 'black', 'brown']
Black picked 182 times.
