shift_right=shift_right >>2 shift_left=shift_left<<2 print bin(shift_right) print bin(shift_left) 比特操作-NOT 1 Just know that mathematically, this is equivalent to adding one to the number and then making it negative. 2 just flips all of the bits in a single number ...
Similarly, if you are generating bits of a string sequentially instead of: s = "" for x in list: s += some_function(x) use slist = [some_function(elt) for elt in somelist] s = "".join(slist) Avoid: out = "" + head + prologue + query + tail + "" Instead, use out = ...
