尝试创建一个for each if循环，用于检查证书是否即将过期

import datetime

certificates = [
    {"name": "Certificate A", "expiry_date": "2022-12-31"},
    {"name": "Certificate B", "expiry_date": "2023-06-30"},
    {"name": "Certificate C", "expiry_date": "2022-09-15"}
]

today = datetime.date.today()

for certificate in certificates:
    expiry_date = datetime.datetime.strptime(certificate["expiry_date"], "%Y-%m-%d").date()
    days_left = (expiry_date - today).days
    
    if days_left <= 30:
        print(f"The certificate {certificate['name']} is expiring soon. Days left: {days_left}")
    else:
        print(f"The certificate {certificate['name']} is not expiring soon. Days left: {days_left}")
