Parse This (Python)

To parse something is to break it down into smaller parts. For example to parse a sentence into words, you break out each word in the sentence.

Objectives

• string processing -- find individual words
• list processing -- keep track of all the words
  • sort the list
• file processing -- read and write files

Program Description

Your program will need to:

• read a text file
• parse the text file into a list of words
• count the number of words in the file
• count the number of 1 letter, 2 letter, 3 letter ... all the way up to 10 letter words. Any word longer than 10 letters will count as a 10 letter word
• count the number of occurrences of each word. Ignore the case (upper and lower case letters are treated as the same).
• output the results to the screen and a new text file.

Program Road Map

1. Read a text file into a string -- to start all words will be written in all lower case characters
2. split the string into a list of words .split()
3. sort the list of words list.sort()
4. count the number of times each word is in the file.
5. count the number of each 1 letter , 2 letter ... words
6. format the output neatly on the screen and in the file
