- Create an array of size 7 of integers 1, -9, 10, 20, 5, 6, 7 . You can set these numbers in the code with initialization. - Write a function that accepts an array and returns the location/index of any value passed to the function. Test it with value 20 and value -1 *HELP: this is linear search - Test it with value 7 and write code in your “main” to see if it is the last element in the array

Write a function (call it get_fh) that receives two arguments: 1). A file name 2). How to open a file for reading or writing ("r", or "w") in Python. The purpose of this function is to open the file name passed in, and pass back the file handle. I can call this function like this: fh_in = get_fh(file_2_open, "r") or fh_out = get_fh(file_2_write, "w") **When using open(), make sure to use try .. except .. except if the open was not successfu the program should raise the right Excpetion(it should raise an IOError for when the file cannot be opened, and raise a ValueError when the wrong argument was passed for the opening mode, e.g. "rrr" instead of "r"). We will test for things like a file that does not exist for opening, or the wrong open mode, e.g. mode='rrr'. See open for more information. All opening and closing of files in your program should use the get_fh function.
