I'm searching line by line for certain tags and then printing the tag
followed by the word immediately following the tag.
So for example, suppose I had the following line of text in a file:
"this is a key test123 noise noise noise noise noise"
In this example, I would want to print "key test123" to a new file.
The rest of the words I would not want.
Here is my code so far:
def test(infile, outfile):
for line in infile:
tagIndex = line.find("key")
start = tagIndex + 4
stop = line[start:].find("\t") -1
if tagIndex != -1:
print("start is: ", start)
print("stop is: ", stop)
print("spliced word is ", line[start: stop])
My question is the following: What is wrong w/ the variable 'stop'?
The index it gives me when I print out 'stop' is not even close to the
right number. Furthermore, when I try to print out just the word
following the tag w/ the form: line[start: stop], it prints nothing
(it seems b/c my stop variable is incorrect).
I would greatly appreciate any help you have. This is a much
simplified example from the script I'm actually writing, but I need to
figure out a way to eliminate the noise after the key and the word
immediately following it are found.
Thank you very much for any help you can provide.
Ben
