How to read complete file with bitstring

I want to read as many 24 bit chunks as possible from a file.
How can I do this using bitstrings’ ConstBitStream
when I don’t now how many chunks there are?

Currently I do this:

eventList = ConstBitStream(filename = 'events.dat')
for i in range(1000) :
    packet =

(here I have to calculate the number of events beforehand)

Best answer

You could read until an ReadError exeption is generated

    while True:
        packet =
except ReadError:
