I wish this helpful for you Currently trying to read the first word of every line , You need to add the first word to a new collection.
code :
var arr = new List<string>();
while ((line = studentsReader.ReadLine()) != null)
{
    arr.Add(line.Split(',')[0]);
}

Text or String written on text file overlaps the previous word. It should write each word line by line

hope this fix your issue The FileOutputStream opens the file in "overwrite" mode, to append to the file use:
code :
FileOutputStream f = new FileOutputStream(file, true);

hope this fix your issue Consider using re.findall() to extract all matched text into a list and for any special characters (like asterisk, *) escape with backslash:
code :
import re

text =  'the text stuff <*to test*> to find a way to extract all text'\
        'that is <*included in special tags*> less than star and greater'\
        'than star'

txtsearch = re.findall('<\*(.*?)\*>', text)

if txtsearch:
    print(txtsearch)

# ['to test', 'included in special tags']

may help you . It looks like you want to divide the file into sentences, not lines. The below code supports both, if you want to split into lines instead of files, simply replace f.read().split('.') with f.read().splitlines()
split your file into sentences:
code :
with open('f1.txt') as f:
    data = f.read().split('.')
searches = ['CEO', 'CTO', 'COO']

for sentence in data:
    if any(i in sentence for i in searches):
        print(sentence)

# Result for your sample input file
Sunder Pichai is the CEO of Google

this will help Read line by line, then split the desired line and get the desired column. This does not perform error checking to make sure the column exists, but does perform error checking in the case that input file has fewer lines than the desired row.
code :
line = []
desired_row = 3
desired_col = 2
value = None
with open (path, 'rt') as input:
    current_line = 1
    for mylines in input:
        if current_line == desired_row:
            value = mylines.split()[desired_col - 1]
            break
        current_line += 1
print(value)
