您可以使用win32com.client模块，下面是一个示例：

import win32com.client
import datetime

# Create an instance of the Windows Calendar COM object
calendar = win32com.client.Dispatch("Outlook.Application")

# Set the reminder details
subject = "MyReminder"
body = "Characteristics of MyReminder"
start = datetime.datetime(2023, 3, 7, 14, 0) 
duration = 60 # in minutes

# Create a new appointment item in the calendar
appointment = calendar.CreateItem(1) # 1 = Appointment

# Set the appointment details
appointment.Subject = subject
appointment.Body = body
appointment.Start = start
appointment.Duration = duration
appointment.ReminderSet = True
appointment.ReminderMinutesBeforeStart = 15 # reminder will appear 15 minutes before the start time

# Save the appointment to the calendar
appointment.Save()
