Question

I am trying to write some code which will open List1.txt and copy the contents up until it sees the string 'John smith' to List2.txt.

This is what I have so far:

F=open('C:\T\list.txt','r').readlines()
B=open('C:\T\list2.txt','w')
BB=open('C:\T\list2.txt','r').readlines()
while BB.readlines() == 'John smith':
    B.writelines(F)

Here is an example of what List1.txt could contain:

Natly molar
Jone rock
marin seena
shan lra
John smith
Barry Bloe
Sara bloe`

However, it doesn’t seem to be working. What am I doing wrong?

Answer 1

F=open('C:\T\list1.txt','r')
B=open('C:\T\list2.txt','w')
for l in F: #for each line in list1.txt
    if l.strip() == 'John Smith':  #l includes newline, so strip it
        break
    B.write(l)

F.close()
B.close()
