$5.$ Bonus Credit Function: Write a Python function called "PrimeBonus" with one input for the filename to write output data. This function should use the output from the prime function $($Problem $3).$ The function loops through all values of n from $1$ to $1000$ and calculates the value of $\backslash (\backslash$mathrm$\{$n$\}^\{\backslash$text $\{$th $\}\}\backslash )$ prime $\backslash (-$p$($n$)\backslash ).$ Your function needs to truncate the value of this difference to one decimal place. To the output filename, the function should write the value of n in the first column and the truncated difference or error in the second column. The first line in the output file should have column headings of $"\backslash ($ n $\backslash )"$ and "Error". The bonus credit function will be graded more harshly than the other functions in this homework. If this function does work you will get zero bonus points.
