Answer 1

I am assuming you Textfile is like below:

    Block1: test is t
    Block2: test is u
    Block3: test is V

You can do it like below:

import re
file = open( "Textfile.txt", "r" ).readlines()
var=raw_input("enter the value")
for line in file:
    if line.find('Block1:') != -1:
        if re.search(var,line,re.IGNORECASE):
            print "value=",line
