Churning Emails - Finding Average of Spam

#1

Hello,

please make me understand the functioning and defining of the logic:

def average_spam_confidence():
with open(’/cxldata/datasets/project/mbox-short.txt’) as fhand:
count = 0
spam_confidence_sum = 0
for line in fhand:
line = line.rstrip()
if line.startswith(‘X-DSPAM-Confidence:’):
var, value = line.split(’:’)
spam_confidence_sum = spam_confidence_sum + float(value)
count = count + 1
return spam_confidence_sum/count
average_spam_confidence()

Hi,

Here, at first you are defining a function to calculate the average spam confidence. Then you open the file mbox-short.txt, from which you pick every line that starts with ‘X-DSPAM-Confidence:’ from which you are picking up the spam confidence that’s given there and calculating it’s total. You are also calculating the total count of the number of lines that starts with ‘X-DSPAM-Confidence:’. Now you dividing the total spam confidence value with the count, and thus you find the average spam confidence.

Thanks.
