Read binary from file

[Larz60+]

Please post entire error traceback verbatim
supple sample file if possible, or where it can be downloaded
b will read 1 byte, starting at byte number 1 in file
You don't show tuppleCounter
is this what you wanted?

You don't need to supply number base to int if decimal
If I try with random binary file:

>>> with open('image_002.jpg', 'rb') as fp:
...     b = fp.read(1)
... 
>>> b
b'\xff'
>>> for x in range( 0,4):
...     tuppleCounter[ ( ( 3 << ( x * 2 ) ) & b ) >> ( x*2 ) ]+=1
... 
Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
NameError: name 'tuppleCounter' is not defined
