$1.$ Create a Python program file called Ch$10-1\_$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$10-1\_$JDoe.py$)$

$$

$2.$ Your program will take a file name from user and find out occurrences of characters $($only alpha numeric characters, no special characters should be included$)$ in the file.$$ Upper and lower characters need to be counted as same characters for this assignment.$$You need to use Python Dictionary and tuples for this assignment.$$ Your output should be sorted ascending order of frequencies.$$ Do not use "Read" method to read the entire file in$.$

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$).$

OUTPUT:
