无效的语法（<未知>，第89行）-pylint（语法错误）

Question

在此字典初始化过程中遇到语法错误，我不知道为什么。

elif user_choice == "H" or user_choice == "h":
    if len(blockchain) >= 1:
        blockchain[0] = {"previous_hash": "", "index": 0, "transactions": [{"sender": "Chris", "recipient": "Max", "amount", 100.0}]}

Answer 1

在您的列表中，amount带有逗号而不是分号：

[{"sender": "Chris", "recipient": "Max", "amount", 100.0}]

应该是：

[{"sender": "Chris", "recipient": "Max", "amount": 100.0}]
