There is a file attached with your assignment, named mailbox-short.txt. Write a program to prompt for a file name, and then read through the file and look for lines of the form: X-DSPAM-Confidence: 0.8475.
When you encounter a line that starts with “X-DSPAM-Confidence:” pull apart the line to extract the floating-point number on the line. Count these lines and then compute the total of the spam confidence values from these lines. When you reach the end of the file, print out the average spam confidence. Your sample output of the program should be:
|
1 2 3 4 |
Enter the file name: mailbox-short.txt Average spam confidence: 0.894128046745 |
Solution:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 |
from os import listdir input_filename = input("Enter the file name: ") tot_line = 0 tot_number = 0 avarage = 0 for filename in listdir('./'): if filename == input_filename: myfile = open(filename, "r") for line in myfile.readlines(): if line.startswith("X-DSPAM-Confidenced: "): tot_line += 1 tot_number = float(tot_number)+ float(line.split(":")[1]) if tot_line > 0: avarage = float(tot_number) / float(tot_line) print("Average spam confidence:", avarage) |
