2 answers:

Make sure there is a function/method to handle the default case. Next, make a dictionary object and store each of the function beginning with the 0th index. After that, write a switch() function accepting the day of the week as an argument.

for i in range( 0 , 5 ):

x = float(input('Enter a number : '))

# add x to arr

arr.append( x )

sum = 0

# find the sum of all elements in arr

for x in arr:

sum += x

# calculate average

average = sum / len(arr)

print('\n%15s %15s\n' %('Original Value' , 'Interest Value'))

for Original_value in arr:

# calculate interesr value

Interest_Value = Original_value * 0.2

print('%10f %15f' %( Original_value , Interest_Value ))

print('\nTotal :', sum)

When an author produce an index for his or her book, the first step in this process is to decide which words should go into the

Igoryamba

Answer:

import string

dic = {}

book=open("book.txt","r")

# Iterate over each line in the book

for line in book.readlines():

tex = line

tex = tex.lower()

tex=tex.translate(str.maketrans('', '', string.punctuation))

new = tex.split()

for word in new:

if len(word) > 2:

if word not in dic.keys():

dic[word] = 1

else:

dic[word] = dic[word] + 1

for word in sorted(dic):

print(word, dic[word], '\n')

book.close()

Explanation:

The code above was written in python 3.

import string 

Firstly, it is important to import all the modules that you will need. The string module was imported to allow us carry out special operations on strings.

dic = {}

book=open("book.txt","r")

# Iterate over each line in the book

for line in book.readlines():

tex = line

tex = tex.lower()

tex=tex.translate(str.maketrans('', '', string.punctuation))

new = tex.split()

An empty dictionary is then created, a dictionary is needed to store both the word and the occurrences, with the word being the key and the occurrences being the value in a word : occurrence format.

Next, the file you want to read from is opened and then the code iterates over each line, punctuation and special characters are removed from the line and it is converted into a list of words that can be iterated over.

 for word in new:

if len(word) > 2:

if word not in dic.keys():

dic[word] = 1

else:

dic[word] = dic[word] + 1

For every word in the new list, if the length of the word is greater than 2 and the word is not already in the dictionary, add the word to the dictionary and give it a value 1.

If the word is already in the dictionary increase the value by 1.

for word in sorted(dic):

print(word, dic[word], '\n')

book.close()

The dictionary is arranged alphabetically and with the keys(words) and printed out. Finally, the file is closed.

You are going to do a bubble sort on the following list. What are the missing members of the list? Select 3 options.

Nadya [2.5K]

The bubble sort makes multiple passes through a list. It compares adjacent items and exchanges those that are out of order. Each pass through the list places the next largest value in its proper place. In essence, each item “bubbles” up to the location where it belongs.
