python3 url解码

有时候我们需要分析一个链接或者dict 但是编码如：‘%7B%22id%22%3A%22bed255d’ 我们就很烦
所以以下就是整理看起来不舒服的字符

from urllib import parse
from urllib import request
import json
a='%7B%22id%22%3A%22bed255dcc2583ef7a0ea2b22013a61ea036cebad%22%2C%22version%22%3A5%2C%22imageUrl%22%3A%22https%3A%2F%2Fimages-na.ssl-image' \

  's%22%3A%5B%7B%22quantity%22%3A19%2C%22quantitySold%22%3A-1%2C%22quantityWaitlisted%22%3A-1%2C%22price%22%3A32.2%2C%22sku%22%3A%22W-ID0089DE-01%22%2C%22ima' \
  'geUrl%22%3A%22https%3A%2F%2Fimages-na.ssl-images-amazon.com%2Fimages%2FI%2F416RLuy0NCL._SCLZZZZZZZ__.jpg%22%2C%22ingressUrl%22%3A%22http%3A%2F%2Fwww.amazon.de' \
  '%2Fb%3Fie%3DUTF8%26node%3D872398%22%2C%22egressUrl%22%3A%22http%3A%2F%2Fwww.amazon.de%2Fdp%2FB07PWD93HC%22%2C%22currencyCode%22%3A%22EUR%22%2C%22asin%22%3A%22B07P' \
  'WD93HC%22%2C%22workgroup%22%3A%22gl_home_improvement%22%7D%5D%2C%22name%22%3A%22edit%22%7D'
a= parse.unquote(a) #解码字符串

a= json.loads(a)
