Python: Exceptions Handling!

-- Write a program that will only accept input from a file provided as the first command line argument. If no file is given or the file cannot be opened, simply print Error opening file! and stop executing.

-- A valid input file should contain two lines. The first line is valid if it contains at least 2 characters ( may be one of these characters), The second line should contain a single integer.

-- The program should then print a single character from the string provided as the first line of input which is at the index given in the second line.

-- If this can't be done for any reason, the program should simply print Error reading input! and stop executing.

(To complete your solution you may use any combination of If-Then statements and Try-Except statements to either prevent exceptions from occurring or catching them when they do occur. Either approach is valid.)

Here are examples of the expected input for the program and there correct output:

-Input- Testing123 7 -Output- 1 -------------------------------------------------------------------------------------------------------- -Input- abcd 75 -Output- Error reading input!
