But when I run the code, the bug appear, the real result as follow: B = [a0, a1, a2,a3 ……,a 1098, a1099] // which has 1100 elements C = [[], []…. []] // which has nothing in each list Then I research the difference between append and extend through google append : ...
Some people pointed out the speed difference between Python 3’srange()and Python2’sxrange(). Since they are implemented the same way one would expect the same speed. However the difference here just comes from the fact that Python 3 generally tends to run slower than Python 2. ...
plt.xlabel('Income difference between treatment and control group') plt.title('Permutation Test'); 排列间的平均差分布 正如我们所看到的,样本统计量相对于置换样本中的值是相当极端的,但并不过分。 卡方检验 卡方检验是一种非常强大的检验,主要用于检验频率差异。

Figure 1:Manually inspecting the difference between two input images (source).可观察左右两张图的不同。 compare_ssim 函数用来计算两张图片之间的结构化相似度。返回两个参数:score和 diff: The score represents the structural similarity index between the two input images. This value can fall into the ...
You’ll find an important behavior difference between methods of immutable objects and methods of mutable objects. For example, string formatting methods always return a new string object because they can’t perform their formatting in place. You’ll typically use these methods in assignments:...
