Alice Put her text watermark into a text:
from text_blind_watermark import TextBlindWatermark
watermark = "绝密：两点老地方见！"
text = "这句话中有盲水印，你能提取出来吗？" * 16
password = "20190808"
twm = TextBlindWatermark(password=password)
twm.read_wm(watermark=watermark)
twm.read_text(text=text)
text_embed = twm.embed()
print("打上盲水印之后:")
