Program Plan Intro

Word Frequency

Program plan:

• Declare a function named “wordfrequency()”.

○ Create an empty dictionary “wDictionary”.

○ Prompt the user for the input file and assign it to “infile”.

○ Open the file in read mode using a handle “fileRead”.

○ Use “for” to iterate the file and strip the lines using “strip()”.

○ Use another “for” loop to iterate the lines and split each line into words using “split”.

○ Use an “if” statement to check whether the word is present in the dictionary keys. When the statement returns true, add the word to the dictionary increment and increment its count; otherwise set its count to “1”.

○ Prompt the user for the output file and assign it to “outfile”.

○ Open the file in the write mode using a handle “fileWrite”.

○ Use a “for” loop to iterate the dictionary and write the word and its frequency to the output file and also print the same in the console.

• In the “main()” function,

○ Call the function “wordfrequency()”.

• Finally, call the “main()” to execute the program.

8. Name and Email Addresses Write a program that keeps names and email addresses in a dictionary as key-value pairs. The program should display a menu that lets the user look up a person’s email address, add a new name and email address, change an existing email address, and delete an existing name and email address. The program should pickle the dictionary and save it to a file when the user exits the program. Each time the program starts, it should retrieve the dictionary from the file and unpickle it.
