给出五个函数式编程的python程序源码

当然，很乐意为您提供五个函数式编程的Python程序源码，如下所示：

1. Map 函数示例：

list_numbers = [1, 2, 3, 4, 5]

def square(x):
    return x ** 2

squared_numbers = list(map(square, list_numbers))
print(squared_numbers)

输出: `[1, 4, 9, 16, 25]`

2. Filter 函数示例：

list_numbers = [1, 2, 3, 4, 5]

def is_even(x):
    return x % 2 == 0

even_numbers = list(filter(is_even, list_numbers))
print(even_numbers)

输出: `[2, 4]`

3. Reduce 函数示例：

from functools import reduce

list_numbers = [1, 2, 3, 4, 5]

def multiply(x, y):
    return x * y

product = reduce(multiply, list_numbers)
print(product)

输出: `120`

4. Lambda 函数示例：

list_numbers = [1, 2, 3, 4, 5]

squared_numbers = list(map(lambda x: x ** 2, list_numbers))
print(squared_numbers)

输出: `[1, 4, 9, 16, 25]`

5. List Comprehension 示例：

list_numbers = [1, 2, 3, 4, 5]

squared_numbers = [x ** 2 for x in list_numbers]
print(squared_numbers)

输出: `[1, 4, 9, 16, 25]`
