Question

Python class

Select a free ebook and download the plain text file (utf8).

Write a program that does the following:

• Read in your ebook (any book, any language)
• Break the book into words (look at .split() for strings)
• Make a dictionary of all words and how often they occur: for instance if the word'the' happened 2000 time and the word'a' happened 1940 times word_dict= {'the' : 2000, 'a' :1940}
• Print the dictionary of word frequencies to a file (freqs.txt) with the most frequent at the top and least frequent at the bottom
• No need to submit the book, I will run it on my own files.

Turn in a .py or Google Colab URL

Dictionaries are not easily sortable since they are not ordered like a list. To sort for this assignment use the following template.

import operator

sorted_dict = sorted(my_dict.items(),key=operator.itemgetter(1))

RAW CODE:

import operator
file = open("file","r") # opening a file in read mode , replace file name with your own file
data = file.read().split() # reading all data and split the data into words using by split() function
dic = {} # empty dic
for word in data: # iterate each word in data
        if word not in dic: # if the word is not present in the dic than add new pair with (word,1) as key and value
                dic[word] = 1
        else: # if the word is already exists in the dic than increment the value of dic[word] 
                dic[word] = dic[word] + 1
sorted_dict = sorted(dic.items(),key=operator.itemgetter(1)) # sorting dictionary based on value
out = open("freqs.txt","w") # opening file in write mode
for item in sorted_dict: # iterate each item(tuple) in sorted_dict
        out.write(str(item[0]) + "\t:" + str(item[1]) + "\n") # write the item data(key and value) into txt file. key = item[0] , value = item[1]
# closing files
file.close()
out.close()
