房间布局和面积的提取

[JKYSTUDY]

由于数据的不规律，爬取贝壳时用下标提取常常会有一些异常值，建议使用正则表达式
pattern_layout = re.compile(r'[0-9]{1,2}[\u4e00-\u9fa5][0-9]{1,2}[\u4e00-\u9fa5][0-9]{1,2}[\u4e00-\u9fa5]')
pattern_size = re.compile(r'([0-9]{1,3})㎡')
descs = desc2.text.strip().replace("\n", "").replace(" ", "").replace("/", "")
m_layout = pattern_layout.search(descs)
m_size = pattern_size.search(descs)
layout = m_layout.group()
size = m_size.group()
