计算2个日期之间的月份天数(python)

from datetime import datetime

def calculate_month_days(start_date, end_date):
    start = datetime.strptime(start_date, '%Y-%m-%d')
    end = datetime.strptime(end_date, '%Y-%m-%d')
    
    # 计算月份差
    months = (end.year - start.year) * 12 + (end.month - start.month)
    
    # 计算每个月份的天数差
    days = []
    for i in range(months + 1):
        # 获取当前月份的最后一天
        last_day = end.replace(day=1) - timedelta(days=1)
        # 计算当前月份的天数差
        days.append(last_day.day - start.day + 1)
        # 更新start为下个月的1号
        start = start.replace(day=1) + timedelta(days=32)
    
    return days

# 示例用法
start_date = '2022-01-15'
end_date = '2022-04-20'
days = calculate_month_days(start_date, end_date)
print(days)
