如何在python中获取从给定年份到当前日期的季度周期？

import datetime

def get_quarters(start_year):
    current_year = datetime.datetime.now().year
    quarters = []

    for year in range(start_year, current_year + 1):
        if year == current_year:
            end_month = datetime.datetime.now().month
        else:
            end_month = 12

        for month in range(1, end_month + 1):
            quarter = (month - 1) // 3 + 1
            quarters.append((year, quarter))

    return quarters

# 示例用法
start_year = 2010
quarters = get_quarters(start_year)
print(quarters)
