WebJun 27, 2024 · 1. @PetrKrampl accuracy of C float (single, 4 bytes) and C double (double, 8 bytes). Python float is really C double. Whatever the accuracy of storing 3.141592654 as a C double, it's lost when it's converted to a C float (by struct.pack) and then back to C double (Python extracts the 4-bytes as a C float and then converts the result back to a C ... WebIf you pass a unicode string to bytes using CPython, it calls PyUnicode_AsEncodedString, which is the implementation of encode; so you're just skipping a level of indirection if you call encode yourself.

WebMar 30, 2012 · 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-masking.
WebPython 3.1 adds a bit_length () method to the int type that does exactly that. Unless you know you are working with numbers that are less than a certain length, for instance numbers from arrays of integers, shifts, rotations, etc. may give unexpected results.
