Question

Write a program to read through the data stored in a file and when you find line that starts with “From”, split the line into words using the split function. We are interested in who sent the message, which is the second word on the From line. IN PYTHON

Answer 1

Note-The editor provided here does not support indentation.It is not accepting the spaces the way I am typing it.That is why am adding the screenshots of the same program as well-to show the indentation.

#program begins
f=open(“filename.txt”,”r”) #opening file names filename.txt in read mode

lines=f.readlines() #lines is a list consisting of all lines in the file

for j in lines: #it will traverse through each line of the file

   if(j[0]==“From”): #if the first word of line is “From”

myline= j.split() #splitting the line which has its first word as From

sender=myline[1] #Extracting the second word of the line and putting it in variable-sender

print(“sender is”,sender) #printing sender’s name
