要實現(xiàn)快遞單號查詢自動識別一天內(nèi)下多少單，首先需要獲取到快遞公司的API接口，然后通過調(diào)用該接口獲取當天的快遞單號數(shù)據(jù)。以下是一個簡單的Python示例：

import requests
from datetime import datetime, timedelta

def get_daily_shipments(api_url):
    today = datetime.now().strftime('%Y-%m-%d')
    headers = {
        'Content-Type': 'application/json',
        'Authorization': 'Bearer YOUR_ACCESS_TOKEN'
    }
    response = requests.get(api_url, headers=headers)
    data = response.json()
    shipments = []
    for item in data:
        shipments.append((datetime.strptime(item['date'], '%Y-%m-%d'), item['number']))
    return shipments

api_url = 'https://example.com/api/shipments'
shipments = get_daily_shipments(api_url)
print(shipments)

請將YOUR_ACCESS_TOKEN替換為實際的API密鑰。這個示例使用了requests庫來發(fā)送GET請求，并使用datetime庫來處理日期和時間。你需要根據(jù)實際情況修改API接口地址和參數(shù)。
