如何确认正在使用多处理库?

如何确认我使用的是库而不是for循环?

from multiprocessing import Pool
from multiprocessing import cpu_count
import requests 
import pandas as pd

data= pd.read_csv('~/Downloads/50kNAE000.txt.1' ,sep="\t", header=None)
data = data[0].str.strip("0    ")

lst = []

def request(x):
    for i,v in x.items():
        print(i)
        file = requests.get(v)
        lst.append(file.text)
    #time.sleep(1)

if __name__ == "__main__":
    pool = Pool(cpu_count())
    results = pool.map(request(data))
    pool.close()  # 'TERM'
    pool.join()   # 'KILL'
