WebSep 29, 2008 · 9 Answers Sorted by: 58 Bitwise operations on Python ints work much like in C. 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.
