如何在包含一些整数和一些字符串的字符串列表中浮动元素？

def sort_mixed_list(mixed_list):
    return sorted(mixed_list, key=lambda x: (isinstance(x, int), x))

mixed_list = [3, "apple", 1, "banana", 2, "cherry"]
sorted_list = sort_mixed_list(mixed_list)
print(sorted_list)  # 输出: [1, 2, 3, 'apple', 'banana', 'cherry']

import re

def extract_number(s):
    match = re.search(r'\d+', s)
    return int(match.group()) if match else float('-inf')

def sort_strings_with_numbers(string_list):
    return sorted(string_list, key=extract_number)

string_list = ["item34", "item12", "item5", "item23"]
sorted_list = sort_strings_with_numbers(string in string_list)
print(sorted_list)  # 输出: ['item5', 'item12', 'item23', 'item34']
