WebDec 3, 2024 · Project description. Python Bit Fields provides simple bit manipulation and bit field construction in Python. Everything is built on the int type so no number functionality is lost, while making it possible to index and slice binary numbers like strings. Color Guard also supports conversion to and from other Python data types. WebBitmasks can be used to manipulate specific bits in a value. For example, you can force Python to represent the sign of an integer using the left-most bit by manipulating the integer with a bitmask. For example, if you perform the AND operation on an integer and a corresponding bitmask, you get the following [1]:

Bit Manipulations in Python — Technical Interview (Part 1)

WebA technique they most certainly used is the manipulation of bitfields for some data structures because they are light and fast, especially much lighter in terms of memory and processing than the Python dictionaries and lists.
