如何在终端内原位刷新多行打印内容，实现加密货币资产动态更新不换行

要实现终端原位刷新多行内容，我们可以通过ANSI控制码移动光标位置逐行覆盖旧输出，同时增加刷新间隔避免接口请求过于频繁被限流，修改后的完整可运行代码如下：

import requests
import time
from datetime import datetime
import os

# 兼容Windows系统终端对ANSI转义码的支持
os.system('')

URL = "https://min-api.cryptocompare.com/data/price?fsym={}&tsyms={}"
# 缓存上次价格，避免请求失败直接报错退出
last_prices = {
    "ETH": 0,
    "DOGE": 0,
    "ADA": 0,
    "SOL": 0
}

def get_price(coin, currency):
    try:
        response = requests.get(URL.format(coin, currency)).json()
        last_prices[coin] = response[currency]
        return response[currency]
    except:
        return last_prices[coin]

first_run = True
# 刷新间隔，单位秒，可自行调整
refresh_interval = 2

while True:
    date_time = datetime.now().strftime("%m/%d/%Y %H:%M:%S")
    eth_price = get_price("ETH", "USD")
    eth_equity = eth_price * 2
    doge_price = get_price("DOGE", "USD")
    doge_equity = doge_price * 100
    ada_price = get_price("ADA", "USD")
    ada_equity = ada_price * 20
    sol_price = get_price("SOL", "USD")
    sol_equity = sol_price * 4
    total_equity = eth_equity + doge_equity + ada_equity + sol_equity

    # 非首次运行时，将光标上移6行，覆盖之前的输出
    if not first_run:
        print('\033[6F', end='')
    
    # 统一格式化输出，固定宽度+保留2位小数，避免内容残留错位
    print(f"ETH  | PRICE: ${eth_price:>7.2f}  EQUITY: ${eth_equity:>8.2f}\033[K")
    print(f"DOGE | PRICE: ${doge_price:>7.2f}  EQUITY: ${doge_equity:>8.2f}\033[K")
    print(f"ADA  | PRICE: ${ada_price:>7.2f}  EQUITY: ${ada_equity:>8.2f}\033[K")
    print(f"SOL  | PRICE: ${sol_price:>7.2f}  EQUITY: ${sol_equity:>8.2f}\033[K")
    print(f" \033[K")
    print(f"更新时间: {date_time} | 总权益: ${total_equity:>10.2f}\033[K", end='\r')
    
    first_run = False
    time.sleep(refresh_interval)

可根据自身需求调整参数：

• 修改各币种权益计算的乘数即可匹配你的实际持仓量
• 修改refresh_interval参数可调整刷新频率，不建议设置低于1秒避免触发接口限流
• 格式化输出的小数位数、对齐宽度都可以按需调整
