Re Split

要从下面字符串中提取rect info

a = ‘Bounding box for object 1 “PAScarSide” (Xmin, Ymin) - (Xmax, Ymax) : (14, 45) - (238, 111)’

得到结果，需要提取的rect info丢失了：

import re

re.split(r’[\s,()-:]+’, a)

[‘Bounding’, ‘box’, ‘for’, ‘object’, ‘“PAScarSide”’, ‘Xmin’, ‘Ymin’, ‘Xmax’, ‘Ymax’, ‘’]

经过调试：

re.split(r’[\s”(,):-]+’, a) [‘Bounding’, ‘box’, ‘for’, ‘object’, ‘1’, ‘PAScarSide’, ‘Xmin’, ‘Ymin’, ‘Xmax’, ‘Ymax’, ‘14’, ‘45’, ‘238’, ‘111’, ‘’]

测试发现只要有[-:]就会有问题，写成[:-]就不会有问题： re.split(r’[\s”(,)-:]+’, a) [‘Bounding’, ‘box’, ‘for’, ‘object’, ‘PAScarSide’, ‘Xmin’, ‘Ymin’, ‘Xmax’, ‘Ymax’, ‘’]

再次测试，发现有[:-)]，[-\s]，[)-\n]等等都会有问题，呵呵:-)
