python 转换 Javascript %u 字符串为python unicode的代码
web采集的数据为 %u6B63%u5F0F%u4EBA%u5458,需要读取并转换为python对象,想了下不调用Javascript去eval,只能自己翻译了。
核心代码:
import re import codecs pattern = re.compile('%u[0-9A-Z]{4}') n = codecs.open('d:\\new.txt', 'w', 'utf-8') with open('d:\\p', 'r') as f: for l in f: for i in pattern.findall(l): l = l.replace(i, unichr(int(i[2:], 16))) n.write(l) n.close()
