- The easiest way to do this is to use the & operator. Convert your message to an int using int(str_msg, 16). convert int to binary string using bin(myint) To get bits 4-6 (from left) in a byte: >> msg = int("10110111", 2) # or 0b10110111 >> extractor = int("00011100", 2) # or 0b10110111 >> result = msg & extractor >> print bin(result) 00010100

The &, | and ^ operators in Python work just like in C. The ~ operator works as for a signed integer in C; that is, ~x computes -x-1. You have to be somewhat careful with left shifts, since Python integers aren't fixed-width. Use bit masks to obtain the low order bits.
In this tutorial, you'll learn how to use Python's bitwise operators to manipulate individual bits of data at the most granular level. With the help of hands-on examples, you'll see how you can apply bitmasks and overload bitwise operators to control binary data in your code.
Sep 2, 2008 · You can use standard slice notation to slice, delete, reverse, overwrite, etc. at the bit level, and there are bit level find, replace, split etc. functions. Different endiannesses are also supported. # Replace every '1' bit by 3 bits. s.replace('0b1', '0b001') # Find all occurrences of a bit sequence.
Feb 18, 2024 · Here’s a simple example of performing some bitwise operations in Python: # Define two numbers in binary. a = 0b1010 # 10 in decimal. b = 0b1100 # 12 in decimal. # Bitwise AND. result_and = a...

Bitwise XOR Operation. Bitwise Right Shift Operation. Bitwise Left Shift Operation. Practical Applications of Bitwise Operations.
Python’s bitwise operators let you manipulate those individual bits of data at the most granular level. Python isolates you from the underlying bits with high-level abstractions. You’re more likely to find the overloaded flavors of bitwise operators in practice.
