运算符的行为会有所不同,具体取决于我运行sage程序的方式。 在笔记本中:
2^10
==>1024
使用sage -python filename.py
运行我的程序:
from sage.all import *
print(2^10)
==> 8
我需要在Python中导入什么来复制Sage笔记本的行为?

感谢大家参加基础Python课程。帝斯曼回答了这个问题 在评论中,sage笔记本有一个预处理器。

在Exponentiation
的python中,我们使用双星号**
>>> print (2**10)
1024
或者您可以使用内置功能 pow 。
>>> pow(2, 10)
1024
<强> POW 强>
pow(...)
pow(x, y[, z]) -> number
With two arguments, equivalent to x**y. With three arguments,
equivalent to (x**y) % z, but may be more efficient (e.g. for longs).

是执行XOR(bitwise exclusive or
)操作的按位运算符。
>>> a = [1,2,3]
>>> b = [3,4,5]
>>> a^b
>>> set(a)^set(b)
set([1, 2, 4, 5])
<强> x ^ y 强>
Does a "bitwise exclusive or".
Each bit of the output is the same as the corresponding bit in x if that bit in y is 0,
and it's the complement of the bit in x if that bit in y is 1.
Just remember about that infinite series of 1 bits in a negative number, and these
should all make sense.
