问题7：列表的拼接

# 方式1：使用+
numbers = []
even = [number for number in range(11) if not number % 2]
odd = [number for number in range(11) if number % 2]
numbers += even + odd
print(numbers)
# [0, 2, 4, 6, 8, 10, 1, 3, 5, 7, 9]

# 方式2：使用list_name.extend(list1)
numbers = []
rights = [1, 3, 5, 7, 8, 10, 12]
numbers.extend(rights)
print(numbers)
# [1, 3, 5, 7, 8, 10, 12]
