WebMar 30, 2012 · 18. You can strip off the leading bit using a mask ANDed with a byte from file. That will leave you with the value of the remaining bits: mask = 0b01111111 byte_from_file = 0b10101010 value = mask & byte_from_file print bin (value) >> 0b101010 print value >> 42. I find the binary numbers easier to understand than hex when doing bit … WebInstead, Python uses a variable number of bits to store integers. For example, 8 bits, 16 bits, 32 bits, 64 bits, 128 bits, and so on. The maximum integer number that Python can represent depends on the memory available. Also, integers are objects. Python needs an extra fixed number of bytes as an overhead for each integer.
