将日期时间范围划分为单独的日期段，例如，访问日期时间范围中存在的每个单独日期的分钟数

from datetime import datetime, timedelta

def calculate_minutes_per_day(start_datetime, end_datetime):
    current_date = start_datetime.date()
    end_date = end_datetime.date()
    minutes_per_day = {}

    while current_date <= end_date:
        next_date = current_date + timedelta(days=1)
        day_start = datetime.combine(current_date, datetime.min.time())
        day_end = datetime.combine(next_date, datetime.min.time())
        
        if day_end > end_datetime:
            day_end = end_datetime
        
        minutes_count = int((day_end - day_start).total_seconds() / 60)
        minutes_per_day[current_date] = minutes_count
        
        current_date = next_date
    
    return minutes_per_day

# 示例使用
start_datetime = datetime(2023, 10, 1, 12, 0)
end_datetime = datetime(2023, 10, 5, 18, 30)
result = calculate_minutes_per_day(start_datetime, end_datetime)
print(result)
