python 正则提取内容

Question

a = """
"productLadderPrices": [

{"formatPrice": "$1.26", "max": 1999, "min": 1000, "price": 1.26},
{"formatPrice": "$1.15", "max": 4999, "min": 2000, "price": 1.15},
{"formatPrice": "$0.98", "max": 19999, "min": 5000, "price": 0.98},
{"formatPrice": "$0.62", "max": -1, "min": 20000, "price": 0.62}

]
"""

上面这段字符串，我要提取中刮号里的内容，也就是"productLadderPrices":[]里面的内容，用python re正则表达式要怎么写呢？

Answer 1

这结构再套上一对大括号就是良好json结构了, 还用啥正则. 直接解析json比较好.
