我怎样才能从这个街区得到一些具体的东西？

Question

所以我把这些信息放在一个列表类中。每当我打印（块）它循环通过整个列表和输出如下：

[{'version': 3, 'from': 'hx7ccc54932b913c71f7051e9dc1b621074c91d462', 'to': 'hxbf2a3504318b6315e38eeb87ee84402361a7d644', 'stepLimit': 1000000, 'timestamp': 1547599428802897, 'nid': 1, 'value': 30000000000000000000000, 'signature': 'ehslHJOj5e6apGhxEbZ6SESx5fagazIPNI5BjCo3sMYAGWVMQbiN8w/PH8BHhHmXBtwEGWiqEuTU5fa4toeOvwE=', 'txHash': '0x833bf64c224209ce850df8f9d47b9b6fcb1471cee93d8c946c2a2bfbded3fb2a'}]

我试过打印（块[1]）和打印（块[0][1]），但它说超出范围？你知道吗

from iconsdk.icon_service import IconService
from iconsdk.providers.http_provider import HTTPProvider

def main():
    icon_service = IconService(HTTPProvider("https://ctz.solidwallet.io/api/v3"))
    block = icon_service.get_block("latest")['confirmed_transaction_list']
    print(block)


if __name__ == '__main__':
    main()

我希望它能给出“to”（hxbf2a3504318b6315e38eeb87ee84402361a7d644）的结果，而不是在整个块中循环，尽管我从未告诉程序这样做。你知道吗

Answer 1

试试这个，拿到钥匙然后打印出来：

from iconsdk.icon_service import IconService
from iconsdk.providers.http_provider import HTTPProvider

def main():
    icon_service = IconService(HTTPProvider("https://ctz.solidwallet.io/api/v3"))
    block = icon_service.get_block("latest")['confirmed_transaction_list']
    print(block[0]['to'])


if __name__ == '__main__':
    main()

那就行了。你知道吗
