插入代码块

使用sum函数：

				?

									numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

									print(sum(numbers))

使用reduce函数：

				?

									# 方式1

									from functools import reduce

									numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

									results = reduce(lambda x, y: x + y, numbers)

									print(results)

									# 方式2

									from operator import add

									from functools import reduce

									numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

									results = reduce(add, numbers)

									print(results)

使用for循环：

				?

									numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

									result = 0

									for number in numbers:

									    result += number

									print(result)

使用递归：

				?

									numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

									def cal(list1, size):

									    if size:

									        return list1[size - 1] + cal(list1, size - 1)

									    return size

									print(cal(numbers, len(numbers)))

列表乘积计算

使用for循环：

				?

									numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

									result = 1

									for number in numbers:

									    result *= number

									print(result)

使用reduce函数：

				?

									# 方式1

									from functools import reduce

									numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

									results = reduce(lambda x, y: x * y, numbers)

									print(results)

									# 方式2

									from operator import mul

									from functools import reduce

									numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

									results = reduce(mul, numbers)

									print(results)

使用递归函数：

				?

									numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

									def cal(list1, size):

									    if size == 0:

									        return 1

									    return list1[size - 1] * cal(list1, size - 1)

									print(cal(numbers, len(numbers)))
