按位移位？ [英] bitwise shift?
问题描述
我找到了这个循环的代码示例。
表示范围内的k（10,25）：
n = 1<< k;
我以前从未读过Python，但是正确的是1乘以
与数字10,11,12,12，...，25假设1<< k表示1班次
留下k这与乘以k相同。
I have found a code example with this loop.
for k in range(10, 25):
n = 1 << k;
I have never read Python before but is it correct that 1 get multiplied
with the numbers 10,11,12,12,...,25 assuming that 1 << k means "1 shift
left by k" which is the same as multiplying with k.

No.
No.
假设1<< k表示由k左移1。
assuming that 1 << k means "1 shift left by k"
是。
Yes.
与乘以k相同。
which is the same as multiplying with k.
No.
尝试启动Python解释器并输入1<< 10.

No.
Try starting the Python interpreter and entering 1 << 10.

1<< n
是一个更有效的替代品
2 ** n

$ b范围内的k为$ b（10,25）：
n = 1<< k;
之前我从来没有读过Python但是1是否正确＃b $ b乘以数字10,11,12,12，这是正确的...假设1 << k
表示由K左移1次这与乘以k相同。

左移+ *与乘以k相同。它与2 ^ k的多元/ b $ b相同。即，1 << 10 = 1024,1 << 11 = 2048,1 << 12 = 4096等。
