# Python怎么查询比特币实时价格
在数字货币交易和量化投资领域,实时获取比特币价格是常见需求。Python凭借丰富的库生态和简洁语法,成为实现这一功能的理想工具。本文将详细介绍4种主流方法,并提供完整代码示例。
## 一、准备工作
在开始前,请确保已安装以下Python库:
```bash
pip install requests pandas ccxt python-binance
import requests
def get_binance_btc_price():
url = "https://api.binance.com/api/v3/ticker/price"
params = {"symbol": "BTCUSDT"}
try:
response = requests.get(url, params=params)
return float(response.json()["price"])
except Exception as e:
print(f"Error: {e}")
return None
print(f"Binance BTC价格: ${get_binance_btc_price():,.2f}")
def get_coingecko_price():
url = "https://api.coingecko.com/api/v3/simple/price"
params = {
"ids": "bitcoin",
"vs_currencies": "usd",
"include_market_cap": "false",
"include_24hr_vol": "false",
"include_24hr_change": "false"
}
try:
response = requests.get(url, params=params)
return response.json()["bitcoin"]["usd"]
except Exception as e:
print(f"Error: {e}")
return None
def get_alpha_vantage_price(api_key):
url = "https://www.alphavantage.co/query"
params = {
"function": "CURRENCY_EXCHANGE_RATE",
"from_currency": "BTC",
"to_currency": "USD",
"apikey": api_key
}
response = requests.get(url, params=params)
return float(response.json()["Realtime Currency Exchange Rate"]["5. Exchange Rate"])
import ccxt
def get_ccxt_price(exchange='binance'):
exchange = getattr(ccxt, exchange)()
ticker = exchange.fetch_ticker('BTC/USDT')
return ticker['last']
print(f"通过CCXT获取的价格: ${get_ccxt_price():,.2f}")
对于高频交易场景,建议使用WebSocket连接:
from binance import ThreadedWebsocketManager
def handle_socket_message(msg):
price = float(msg['c']) # 最新成交价
print(f"实时价格更新: ${price:,.2f}")
twm = ThreadedWebsocketManager()
twm.start()
twm.start_symbol_ticker_socket(
symbol="BTCUSDT",
callback=handle_socket_message
)
# 运行30秒后停止
import time
time.sleep(30)
twm.stop()
获取价格后通常需要存储和分析:
import pandas as pd
from datetime import datetime
price_history = []
def save_price(price):
price_history.append({
"timestamp": datetime.now(),
"price": price
})
# 转换为DataFrame
df = pd.DataFrame(price_history)
# 保存到CSV
df.to_csv("btc_prices.csv", index=False)
return df
# 示例使用
latest_price = get_binance_btc_price()
if latest_price:
df = save_price(latest_price)
print(df.tail())
import time
import schedule
from plyer import notification # 用于桌面通知
def price_monitor():
price = get_binance_btc_price()
if price:
message = f"BTC当前价格: ${price:,.2f}"
print(message)
# 桌面通知(仅Windows/macOS)
notification.notify(
title="比特币价格提醒",
message=message,
app_icon=None,
timeout=10
)
save_price(price)
# 每5分钟运行一次
schedule.every(5).minutes.do(price_monitor)
while True:
schedule.run_pending()
time.sleep(1)
通过以上方法,您可以轻松地将比特币实时价格集成到您的Python应用中。根据需求选择合适的方式——简单查询用REST API,高频交易用WebSocket,长期分析建议建立本地数据库存储历史数据。 “`
