Python列表推导式（List Comprehensions）是一种简洁、高效的创建列表的方法。以下是一些常用的应用技巧：
squares = [x**2 for x in range(1, 6)]
even_numbers = [x for x in range(1, 11) if x % 2 == 0]
strings = ['hello', 'world']
uppercase_strings = [s.upper() for s in strings]
matrix = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
flattened_matrix = [[element for element in row] for row in matrix]
squares_generator = (x**2 for x in range(1, 6))
even_squares = [x**2 for x in range(1, 6) if x % 2 == 0]
nested_list = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
flattened_list = [element for sublist in nested_list for element in sublist]
这些技巧可以帮助你更有效地使用Python列表推导式来简化代码并提高性能。
