如何在一列的所有值中只让4个值跟在点后面？

def add_dot_to_values(values):
    count = 0
    result = []
    for value in values:
        if isinstance(value, (int, float)):
            value = str(value) + "."
            count += 1
        result.append(value)
        if count == 4:
            break
    return result

# 示例数据
values = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

# 调用函数并输出结果
result = add_dot_to_values(values)
print(result)
