$1.$ Create a Python program file called Ch$09-2\_$Name.py$.($Replace Name with your initial of first name and first $5$ letters of last name.$$ If your last name is shorter than $5$ letters, just use full last name, it doesn't have to be $5$ letters.$$ i$.$e$.$ if your name is John Doe, your file name should be Ch$09-2\_$JDoe.py$)$

$$

$2.$ Your program will take a file name from user and find out occurrences of words in the file.$$ Case shouldn't matter, i$.$e$.$ "the" and "The" should be counted as same word.$$ Your output should list each word and occurrences of it in the file.$$ Also, at the end, your program needs to print out number of different words in the file.$$ You need to use Python Dictionary for this assignment.$$ Make sure to exclude special characters.$$ But words like "don't", "we'll" should be counted the way they are.$$ Upper case and lower case letters should be treated the same, $($i$.$e$.$ "But" and "but" should be counted as same word$)$

Then output list of words and their occurrences in alphabetical order.$$ One word per line with occurrences.$$

If user enters wrong information $($wrong name of the file or non$-$existing file name$),$ your program needs to display message and ask for correct input.$$ Your program should not generate traceback message with any input.

Your program's output should be exactly same or very close to the sample output provided.$$ Output should be formatted to match the sample output provided or points will be deducted $($up to $8$ points$).$
