This seems to be right everywgere But I am getting IndexError everytime at the bin_bash line. but with the...

This gives me

The field "Title" is for a short title only. A full explanation goes in the much larger field.

If you get a list index out of range on [0] then the list is empty, and contains no value. You can check if a list has any values in it using not, e.g.:
my_list = function_that_returns_a_list()
if not my_list:
print("Your list is empty")
else:
print(my_list[0])
Verify that your re.findall('useful_string: (.*)', prompt) isn't returning an empty list.

You're probably right I've a C code and compiled binary file in the same directory which has "useful_string" let me add my C code so you can have a better look at it.

I don't know C well enough to see what data that will parse to your Python script. You'll have to make a different question with different tags - I've answered this one as best I can.
