如何将列表写入没有括号的csv列中？

Question

I want to make a csv, where each row contains certain "single" variables (photo_paths[i], i, p, norm_ratio) and then many columns of list items (point_values).

face_writer = csv.writer(csvfile, delimiter=',', quotechar='|', quoting=csv.QUOTE_MINIMAL)
face_writer.writerow([photo_paths[i], i, p, norm_ratio, point_values])

the resulting first and last items in the list contain brackets and a vertical bar:

|[20.426487199475673
 5986.817702828149]|

all the others in the middle are fine.

how do I get rid of those symbols?

Answer 1

The argument to writerow() should be a 1-dimensional list of all the fields. point_values is a list, and you're nesting it inside the list. You shold concatenate it instead:

face_writer.writerow([photo_paths[i], i, p, norm_ratio] + point_values)
