Modify the code in PracTest$1.$py $($see on right$)$ to:

$1.$ Correct any errors $-$ get the given code working

$2.$ Print alternating $+$ and $|$ characters $($see sample output on right$)$

$3.$ On each row, use a for loop to print the required $+$ or $---$ characters

$4.$ Add to code to have the user enter the number of rows and columns

$5.$ For each user entry, test that it is in a valid range, use a loop to

ask them to re$-$enter the year and continue looping until it is valid, You can

assume the user enters an integer

$6.$ After printing the grid, ask the user to enter a row and column within the grid

$($validate that the numbers are in range $$ counting from zero$)$

$7.$ Print the grid again with an X in that position

$8.$ Test your code with valid and invalid entries
