Question

python

Write the function getSpamLines(filename) that read the filename text file and look for lines of the form 'SPAM-Confidence: float number'. When you encounter a line that starts with "SPAM-Confidence:" extract the floating-point number on the line. The function returns the count of the lines where the confidence value is greater than 0.8. For example, if 'spam.txt' contains the following lines along with normal text getSpamLines('spam.txt') returns 2. SPAM-Confidence: 0.8945 Mary had a little lamb. SPAM-Confidence: 0.8275 SPAM-Confidence: 0.7507 The lamb is sure to go.

def getSpamLines(filename):#definition of function

    filename=open("spam.txt","r")#open file in read mode

    list1=[]#declare list1=[],list2=[] and count=0

    list2=[]

    count=0

    for lines in filename:#so for each line in filename split it

        for word in lines.split():

                list2.append(word)#and append each word to the list2

        list1.append(list2)#append list2 to list1

        list2=[]#again put list2=[]

    #print(list1)

    for i in list1:#for each element in list1

        for ele in range(len(i)):#for element in i

            #print(i[ele])

            if (i[ele]=="SPAM-Confidence:"):#if ele is SPAM-Confidence:

                if(float(i[ele+1])>0.8):#then it finds the value of SPAM-Confidence:

                    count=count+1#if it is greater than 0.8 it increments count

    return count#it returns number of line which are having SPAM-Confidence:>0.8

print(getSpamLines("spam.txt"))#calling the function
