如何仅对末尾带有数字的字符串进行切片

import re

def slice_numeric_strings(strings):
    pattern = r'\d+$'
    sliced_strings = []
    for string in strings:
        match = re.search(pattern, string)
        if match:
            sliced_strings.append(string[:match.start()])
        else:
            sliced_strings.append(string)
    return sliced_strings

# 示例输入
strings = ['hello123', 'world456', 'foo', 'bar789']

# 调用函数进行切片
sliced_strings = slice_numeric_strings(strings)

# 输出结果
print(sliced_strings)

['hello', 'world', 'foo', 'bar']
