本函数可找出列表中缺失的数，方法如下：1. 创建列表中所有数的集合；2. 创建从 1 到列表中最大数的所有数的列表；3. 通过从所有数的列表中减去集合中的数，找出缺失的数。
<code class="python3">def find_missing_numbers(nums):
"""
Finds all the missing numbers in a list of integers.
Args:
nums: A list of integers.
Returns:
A list of all the missing numbers in the list.
"""
# Create a set of all the numbers in the list.
num_set = set(nums)
# Create a list of all the numbers from 1 to the maximum number in the list.
max_num = max(nums)
num_list = list(range(1, max_num + 1))
# Find the missing numbers by subtracting the set of numbers in the list from
# the list of all numbers.
missing_nums = list(set(num_list) - num_set)
return missing_nums</code>以上就是python3源代码的详细内容，更多请关注php中文网其它相关文章！
