Question

我对regexp没有多少经验，所以需要在这里提出问题。

我正在为学习算法上传数据库。有五个变量：迭代，标签，像素强度矢量，坐标矢量和边界框坐标。

我以这种方式上传了像素矢量：

with open(tracked_cow, 'r+') as f:
    ...
     elif line % 5 == 2:
     # regular expression
     string_this_obs = [float(val) for val in re.findall(r"[\d.]+", vs)]
     mean_intensities.append(string_this_obs)

获取浮标中每个观察的强度列表，这正是我需要的。每个观察的坐标格式为[(v1,v2), (v3,v4)...]，我希望获得类似['(v1,v2)','(v3,v4)'...]的内容，其中每个输入都是一个字符串。

编辑：这是来自文件的原始数据：
