如何计算周末的天数

import datetime

def count_weekend_days(start_date, end_date):
    count = 0
    current_date = start_date
    while current_date <= end_date:
        if current_date.weekday() >= 5:  # 5和6分别代表周六和周日
            count += 1
        current_date += datetime.timedelta(days=1)
    return count

start_date = datetime.date(2022, 1, 1)
end_date = datetime.date(2022, 12, 31)
weekend_days = count_weekend_days(start_date, end_date)
print("2022年共有", weekend_days, "个周末天数。")
