Hi, Below is my output:

From this output I want get only 0,1,2,3,1,2,3,1,1,1,1,2,1,1,4,5,1,2,1,1 only when I am printing 3 array index then some cases I am getting MFPCI and 1291103C.1290103C. Please let me know how can I get this value??????

The problem is that not all the data has the same format and the numbers you are looking for are in different "array" positions for some lines if you split those lines based on whitespace. For example:
DE 15E0 TTA: 1 Generic Com port => Number 1 is at offset 3
FF 0 1 MFPCI => Number 1 is at offset 2

Note that when the number you want is at offset 3, then the data at offset 2 is a non-numeric value ending with ":"

You could take advantage of this by:
For each line, split based on whitespace and examine the data at offset 2. If it does not end with a ':' then you can use this as your value otherwise take the data at offset 3.

Hi, Thanks for ur reply but I tried everything and not getting the desired output. Even I am new to Python also so I don't know how to proceed thru ur logic. It would be great if u can send me some working code. Thanks Krishna_sicsr

Here you go, let me know if you need any more help. Note that I'm assuming that the data has been read into an array called lines with each line of text as a separate array entry. The code below gives you the desired numbers.

for line in lines:
    parts = line.split()
    if parts[2][-1] == ':':
        print parts[3]
    else:
        print parts[2]
