count the number of each word in the document and store the word and its count in a dictionary, with the word as the Key and the count as the Value.

Lab Assignment Prompt:  News Editor-in-Chief 

 

As the news editor, who also happens to have some Python skills, your role requires a weekly review of your reporters’ work and make sure it communicates clearly to your audience.  Some of this work is repetitive - especially finding those words and phrases that authors tend to frequently reuse.  

 

To save yourself some time, and improve complete the weekly review faster, you will create a python program to:

Inspect a text document provided by any author/reporter. 

Count the number of times each word appears in the text.  (Common articles, such as a, an, the, may be ignored)  

Search for a specific word and replace it with something different. 

Open a file, operate upon, and save a new version of, a text file stored locally on your computer.

 

NOTE:  Run ALL of the code you created and make sure it works as intended (WAI).

 

Program Requirements:

 

Import a document

Count the number of total words in the document.

Unit 1: Numeric operations

Unit 2: Variables

Count the number of each word in the document and store the word and its count in a dictionary, with the word as the Key and the count as the Value.

Unit 6: Dictionaries

Unit 5: Loops

Unit 2: Assignments and shortcut operators 

Unit 2: Variables

Unit 1: Numeric operations

NOTE: this requirement is basically the dictionary counting trick.

 

Assignment continues on the following page.

 

 

Include a way to exclude common but unimportant words, such as “a”, “an”, “the”.  The user of your code can input a list of these unimportant words and there can be as many as the user would like to ignore.

Unit 4: Lists

Unit 3: Functions (optional parameters)

Unit 5: Loops

Unit 6: Dictionaries, Keys, looping through keys using list elements

Store a second dictionary with each word’s proportion as a float with four decimals, of the text’s total words.  For example, if the word, “weather” is found 143 times out of 5390 total words, the proportion will be calculated as 143 / 5390, and the value will be 0.0265.

Unit 6: Dictionaries

Unit 5: Loops

Unit 2: Assignments

Unit 2: Variables

Unit 1: Numeric operations

NOTE: this requirement is basically a twist on the dictionary counting trick, so students can’t just copy the counting trick.  But they can get close to this.

Accept a user’s query of whether a word exists in the text.  If the word search finds a word, state the word, the number of times it appears, and the proportion of total words made up by that word.  If the word does not find the word, return some information that the word was not found in the text. 

Unit 6: Dictionaries – using Key In / Not In

Unit 4: Lists – using In / Not In

Unit 6: Dictionaries – basic call of a K/V pair

Unit 2: Conditional Statements

Accept a user’s request to list the top n words in the text.  (The user chooses how many.)  The code will print the word, the absolute count, and the proportion of those words - each on its own line.

Unit 6: Dictionaries

Unit 4: Lists (possibly, to extract the list of keys from a dictionary and slice the top n)

Unit 2: Conditional Statements
