I need to create three text file for the above(Note: I have got a very large here for example I have shown for three) . 

import os
filepath=os.path.normpath('C:\\Users\\abc.txt')
with open(filepath,'r') as rf:
    for index,line in enumerate(rf):
        with open ('filename{}.txt'.format(index),'w') as output:
            while(line!=""):
                output.write(line)

Try replacing while(line!=""): with while(line!="\n"):

import os
filepath=os.path.normpath('C:\\Users\\abc.txt')
with open(filepath,'r') as rf:
    record = 1
    output = open('filename{}.txt'.format(record), 'w')
    for line in rf:
        if line == "\n":
            record += 1
            output.close()
            output = open('filename{}.txt'.format(record), 'w')
        else:
            output.write(line)

Or simpler:

awk -v RS= '{print > ("filename" NR ".txt")}' abc.txt

Optimized way:

import os

def get_file(idx):
    ''' Opens file in write mode using `idx` arg as filename suffix.
        Returns the file object created
    '''
    fn = 'filename{}.txt'.format(idx)
    return open(fn, 'w')    

with open(os.path.normpath('C:\\Users\\abc.txt'), 'r') as f:
    idx = 1
    out_file = get_file(idx)
    for l in f:
        if not l.strip():
            out_file.close()
            idx += 1
            out_file = get_file(idx)
        else:
            out_file.write(l)
