NameError: name ‘null’ is not defined 解决方案

[
{
"id": 1,
"juzi": "熟悉的地方没有风景",
"from": "网络",
"from_who": null,
}
]

我想把这样的字符串转换成字典

发现 python无法处理null这样的字符串

null = ""
a = """[
{
"id": 1,
"juzi": "熟悉的地方没有风景",
"from": "网络",
"from_who": null,
}
]"""
a = eval(a)
print(a)

[{'id': 1, 'juzi': '熟悉的地方没有风景', 'from': '网络', 'from_who': ''}]

Process finished with exit code 0

只要在前面添加一句

null = ""
