A right shift by n bits is defined as division by pow(2,n ) . A left shift by n bits is defined as multiplication with pow(2,n ) ; for plain integers there is no overflow check so in that case the operation drops bits and flips the sign if the result is not less than pow(2,...

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 ...

ValueError: negative number cannot be raised to a fractional power 这些异常、错误, 发现里边有很多细节问题: python中,想要表示a的b次方时,有两种方法: 1,math.pow()这个内置函数 2,**运算符 这两种方法效果是一样的,但是当 b为分数,a为负数:当幂运算符的底数为负数、幂为分数时,Python会抛出ValueError:...
