从列表中的每个值中减去动态值

# 假设我们有一个列表和一个动态值
data_list = [10, 20, 30, 40, 50]
dynamic_value = 5

# 使用列表推导式进行减法操作
result_list = [x - dynamic_value for x in data_list]

print(result_list)  # 输出: [5, 15, 25, 35, 45]

# 检查并过滤非数字元素
filtered_list = [x for x in data_list if isinstance(x, (int, float))]
result_list = [x - dynamic_value for x in filtered_list]

print(result_list)  # 输出: [5, 15, 25, 35, 45]

import multiprocessing as mp

def subtract_dynamic_value(x):
    return x - dynamic_value

with mp.Pool(mp.cpu_count()) as pool:
    result_list = pool.map(subtract_dynamic_value, filtered_list)

print(result_list)  # 输出: [5, 15, 25, 35, 45]
