在列表理解中使用条件

# 示例1：筛选出列表中大于等于5的元素
numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
filtered_numbers = [x for x in numbers if x >= 5]
print(filtered_numbers)
# 输出: [5, 6, 7, 8, 9, 10]

# 示例2：筛选出字符串列表中长度大于等于5的字符串
words = ["apple", "banana", "orange", "kiwi", "grape"]
filtered_words = [word for word in words if len(word) >= 5]
print(filtered_words)
# 输出: ['apple', 'banana', 'orange']

# 示例3：筛选出字典列表中值为偶数的字典
data = [{"name": "Alice", "age": 25}, {"name": "Bob", "age": 30}, {"name": "Charlie", "age": 35}]
filtered_data = [item for item in data if item["age"] % 2 == 0]
print(filtered_data)
# 输出: [{'name': 'Bob', 'age': 30}]
