如何将十亿或百万缩写字符串转换为列表中的整数

import re

def convert_to_integers(strings):
    integers = []
    pattern = r'(\d+(\.\d+)?)([KMB])'
    
    for string in strings:
        match = re.match(pattern, string)
        if match:
            number = float(match.group(1))
            abbreviation = match.group(3)
            
            if abbreviation == 'K':
                number *= 1000
            elif abbreviation == 'M':
                number *= 1000000
            elif abbreviation == 'B':
                number *= 1000000000
            
            integers.append(int(number))
    
    return integers

strings = ['1.5K', '2.3M', '3.7B']
integers = convert_to_integers(strings)
print(integers)  # 输出：[1500, 2300000, 3700000000]
