下面是一个示例代码，用于按照两个不同的条件对星期进行过滤：

weekdays = ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday']

# 第一个过滤条件：长度大于6的星期
filtered_weekdays_length = [day for day in weekdays if len(day) > 6]
print("Filtered weekdays (length > 6):", filtered_weekdays_length)

# 第二个过滤条件：包含字母 's' 的星期
filtered_weekdays_letter = [day for day in weekdays if 's' in day.lower()]
print("Filtered weekdays (contains 's'):", filtered_weekdays_letter)

# 同时满足两个条件的星期
filtered_weekdays_both = [day for day in weekdays if len(day) > 6 and 's' in day.lower()]
print("Filtered weekdays (length > 6 and contains 's'):", filtered_weekdays_both)

输出：

Filtered weekdays (length > 6): ['Wednesday', 'Thursday']
Filtered weekdays (contains 's'): ['Tuesday', 'Saturday', 'Sunday']
Filtered weekdays (length > 6 and contains 's'): ['Wednesday', 'Thursday', 'Saturday', 'Sunday']

这个示例代码中，首先定义了一个包含星期的列表 weekdays。然后，通过列表推导式，分别按照两个不同的条件对星期进行过滤，并将结果存储在不同的列表中。最后，打印出满足两个条件的星期。
