如何将每个供应商名称的所有借项、贷项相加，并获得余额

# 示例交易记录
transactions = [
    {"supplier": "Supplier A", "debit": 100, "credit": 50},
    {"supplier": "Supplier B", "debit": 200, "credit": 150},
    {"supplier": "Supplier A", "debit": 50, "credit": 0},
    {"supplier": "Supplier C", "debit": 300, "credit": 200}
]

# 创建字典并初始化借项总额和贷项总额为0
balances = {}
for transaction in transactions:
    supplier = transaction["supplier"]
    balances[supplier] = {"debit": 0, "credit": 0}

# 计算借项总额和贷项总额
for transaction in transactions:
    supplier = transaction["supplier"]
    debit = transaction["debit"]
    credit = transaction["credit"]
    balances[supplier]["debit"] += debit
    balances[supplier]["credit"] += credit

# 计算余额并输出结果
for supplier, balance in balances.items():
    debit_total = balance["debit"]
    credit_total = balance["credit"]
    remaining_balance = debit_total - credit_total
    print(f"Supplier: {supplier}")
    print(f"Remaining Balance: {remaining_balance}")
