如何提取旁边带有符号的值(例如*)

def extract_value_with_symbol(string):
    symbol = "*"
    values = []
    
    for i in range(len(string)):
        if string[i] == symbol:
            start = i - 1
            end = i + 1
            
            while start >= 0 and string[start] != " ":
                start -= 1
                
            while end < len(string) and string[end] != " ":
                end += 1
                
            value = string[start+1:end]
            values.append(value)
    
    return values

import re

def extract_value_with_symbol(string):
    pattern = r'\b\w+\*+\w+\b'
    matches = re.findall(pattern, string)
    
    values = []
    
    for match in matches:
        value = match.replace("*", "")
        values.append(value)
        
    return values
