This is need coding with : Python v3 Your program should be able to read a file and then counts the word frequencies as well as the letter frequencies. Results should be stored in the two global variables. You will need at least 4 functions where one is already given:

cleanupLine(line)

- accepts one line and removes characters that are not needed. Unwanted characters are all characters except a-z, A-Z, 0-9 and '. They should be replaced with a space.

Samples:

long-term -> long term

It's amazing, isn't it? -> It's amazing isn't it

countWords(line)

- For a stripped line, this function counts the words and updates the global variable wordsDict{}. For instance, the line "Hello hello World" should update wordsDict to {'hello' : 2, 'world' : 1}.

Note, we convert upper case letters to lower case

countLetters(line)

- For a stripped line, this function counts the letters and updates the global variable lettersDict{}. For instance, "hell" should update to lettersDict {'h' : 1, 'e' : 1, 'l' : 2}

Note, we convert upper case letters to lower case.

Note2, numbers and ' should be ignored"""

Please process the textfiles on your machine and then have a last function named results() returning a list with the frequencies as follows:

e for file1, t for file2 and w for file3 followed by the frequency of

"to" for file1, "the" for file2 and "computer" for file3.

Pseudocode e.g.:

return [e for file1, t for file2, w for file3, "to" for file1, "the" for file2, "computer" for file3]

might look like:

return [1234, 123456, 213, 123556, 122, 53421]
