Make a .py file called Fx_4. Then, perform the following exercise:

Write python code that accepts string inputs formatted such as the following:

str = X-DSPAM-Confidence:0.8475

Use find and string slicing to extract the portion of the string after the colon character and then use the float function to convert the extracted string into a floating point number. Keep a sum of all the confidence values extracted.

Put this code in a loop than runs until the user enters quit or QUIT. When the user quits, print out the average X-DSPAM-Confidence. Bad input (input that isnt quit OR doesnt have a confidence as above) should be rejected appropriately.
