PYTHON :制作一个包含 4 列的列表和 2 个包含 2 列的列表

PYTHON : Make a list of 4 columns with 2 lists of 2 columns

如果问题已经回答了,我真的很抱歉,我没有找到正确的主题... 我正在与 Pavlovia 和 Pyschopy 合作。

我希望我的参与者将鼠标光标保持在移动框(目标)内。 我正在记录数据,我想:

  1. 记录鼠标和目标的位置
  2. 计算每帧鼠标与目标中心的距离
  3. 计算鼠标开箱的频率

问题在第 1 步和第 2 步之间:

但我无法在 1 个文件中找到 4 列的位置(鼠标 x;鼠标 y;目标 x;目标 y)

我的问题与 :

非常相似

但它无法正常工作

列表看起来像:

我想得到 [['x1', 'y1'], ['xA', 'yA'], ['x2', 'y2'],['xB', 'yB'],[...]]

但是当我可以加入列表时,我只有类似的东西 [['x1', 'y1'], ['x2', 'y2'], ['xA', 'yA'], ['xB', 'yB'],[...]]:-(

我想我不明白二维列表是如何工作的,但我已经阅读了很多课程和教程,但我没有诀窍:(

谢谢你

编辑: 这是我的结果: [item for sublist in zip(Mouse, Target) for item in sublist]

所以,我想,我需要 [['x1', 'y1', 'xA', 'yA'], ['x2', 'y2','xB', 'yB'],[...]]

编辑 2: 感谢 Akshay Sengal!

您可以使用 zip 执行此操作,然后将其展平以取回物品。您可以按元素压缩 2 个列表(将两个列表的相应元素一起添加到一个元组中。

Post,您可以使用 [item for sublist in list for item in sublist],它可以让您 flatten 并将元组分解为相应的项目。

列出这个 -

Mouse = [['x1', 'y1'], ['x2', 'y2']]
Target = [['xA', 'yA'], ['xB', 'yB']]

[item for sublist in zip(Mouse, Target) for item in sublist]
[['x1', 'y1'], ['xA', 'yA'], ['x2', 'y2'], ['xB', 'yB']]

编辑:

根据你更新的问题,你可以这样做 -

Mouse = [['x1', 'y1'], ['x2', 'y2']]
Target = [['xA', 'yA'], ['xB', 'yB']]

out = [i+j for i,j in zip(Mouse, Target)]
out
[['x1', 'y1', 'xA', 'yA'], ['x2', 'y2', 'xB', 'yB']]

仅供那些想要测试我的代码的人使用,合并后的文件可与 i[0],i[1],j[0],j[1] 而不是 i+j

#data to be written row-wise in csv file
dataF = [[i[0],i[1],j[0],j[1],k,abs(i[0]-j[0]),abs(i[1]-j[1])] for i,j,k in zip(MposList,Tdata,mIOt)]

列表的 type/dimension 无法使用正常代码,我添加了 x 和 y
