Traceback (most recent call last):
  File "C:\Users\RAC\crypto\...\blockchain.py", line 178, in <module>
    blockchain = Blockchain()
                 ^^^^^^^^^^^^
  File "C:\Users\RAC\crypto\...\blockchain.py", line 49, in __init__       
    self.chain = [self.create_genesis_block(0)]
                  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: Blockchain.create_genesis_block() takes 1 positional argument but 2 were given

代码是这样的

class Blockchain:
    def __init__(self):
        self.chain = [self.create_genesis_block(0)]
        self.difficulty = 4
        self.nodes = dict()
        self.replicated_nodes = dict()
        self.coin_ledger = dict()

    def create_genesis_block(self):
        return Block("Genesis Block", "0", coin)

我试着添加其他参数，但由于我是新来的，我自己还没能正确地弄清楚

def create_genesis_block(self):不带参数，可能您的意思是：

def create_genesis_block(self, block_num):
        return Block("Genesis Block", block_num, coin)

或

@staticmethod 
def create_genesis_block(block_num):
        return Block("Genesis Block", block_num, coin)

使用self构造函数时，需要初始化类，请尝试

instanse = Blockchain()
instanse.create_genesis_block()
