Write a program that 1 Prompts for a filename 2. Then opens that file and reads through it, looking for lines like X-DSPAM-Confidence 3. Extract the floating-point values from the end of each of the lines 4. Sum the total 5. Count how many lines 6. Compute the average of those values and produce output like: Count: 27 Mean 15: 0.7507185185185187 Hints: Do not use the sum() function or a variable named sum in your solution. You'll need to loop through the file Use a string method (like "startswith" to help parse the file) see the Py3 Docs String splicing to get the value out. See how long the X-DSPAM-Confidence: 0.8475 string is and extract the number . After splicing out the value be sure to make the value a float You'll need to create variables to hold the count and totals to be used at the end to computer the (mean average
