Python 我想将这些数据从spark rdd转换为听写

数据就像一本字典，但放在方括号内，这使它成为一个列表。 名单如下：

---

a=[{'sI'：['17046'，'17043']，'sQ'：['15800'，'15789']，'rid'：572，'pid'：511，'uid'：411，'st'：1594892854.513586，'et'：'16

如果您的原始数据是一个元素列表，那么您应该只使用零索引，您将获得字典

代码：

raw_data = [
    {
        "sI": ["17046", "17043"],
        "sQ": ["15800", "15789"],
        "rid": 572,
        "pid": 511,
        "uid": 411,
        "st": 1594892854.513586,
        "et": "16",
    }
]

print("Raw type: {}".format(type(raw_data)))

converted_data = raw_data[0]  # Get the first element of list.

print("Converted type: {}".format(type(converted_data)))

>>> python3 test.py
Raw type: <class 'list'>
Converted type: <class 'dict'>

raw_data = [
    {
        "sI": ["17046", "17043"],
        "sQ": ["15800", "15789"],
    },
    {
        "sI": ["2", "3"],
        "sQ": ["4", "5"],
    }
]  # This list contains 2 dicts

print("Raw type: {}".format(type(raw_data)))

for item in raw_data:
    print("Type inside loop: {}".format(type(item)))  # Getting dicts one-by-one ("item" variable contains it)

>>> python3 test.py
Raw type: <class 'list'>
Type inside loop: <class 'dict'>
Type inside loop: <class 'dict'>

输出：

raw_data = [
    {
        "sI": ["17046", "17043"],
        "sQ": ["15800", "15789"],
        "rid": 572,
        "pid": 511,
        "uid": 411,
        "st": 1594892854.513586,
        "et": "16",
    }
]

print("Raw type: {}".format(type(raw_data)))

converted_data = raw_data[0]  # Get the first element of list.

print("Converted type: {}".format(type(converted_data)))

    },
    {

    }
]  # This list contains 2 dicts

如果您提供一个有效的Python列表就好了。其他人无法确定您的列表是否只包含一个或多个元素。
