如何从字符串中提取数字并使用它们从YAML文件中提取

import re
import yaml

def extract_numbers_from_string(string):
    numbers = re.findall(r'\d+', string)
    return [int(num) for num in numbers]

def extract_numbers_from_yaml(yaml_file):
    with open(yaml_file, 'r') as file:
        data = yaml.safe_load(file)
        numbers = []
        for key, value in data.items():
            if isinstance(value, str):
                numbers.extend(extract_numbers_from_string(value))
        return numbers

# 示例用法
string = "abc123def456xyz"
yaml_file = "example.yaml"

extracted_numbers = extract_numbers_from_string(string)
print("提取的数字：", extracted_numbers)

extracted_numbers_from_yaml = extract_numbers_from_yaml(yaml_file)
print("从YAML文件中提取的数字：", extracted_numbers_from_yaml)
