how to make the following for loop use multiple core in Python?

Question

That's a normal Python Code which is running normally

import pandas as pd
dataset=pd.read_csv(r'C:\Users\efthi\Desktop\machine_learning.csv')
registration = pd.read_csv(r'C:\Users\efthi\Desktop\studentVle.csv')


students = list()
result = list()
p=350299
i =749
interactions = 0 
while i <8659:
    student = dataset["id_student"][i]
    print(i)
    i +=1
    while p <1917865:
        if student == registration['id_student'][p]:
            interactions += registration ["sum_click"][p]
        p+=1
    students.insert(i,student)
    result.insert(i,interactions)
    p=0
    interactions = 0


st = pd.DataFrame(students)#create data frame 
st.to_csv(r'C:\Users\efthi\Desktop\ttest.csv', index=False)#insert data frame to csv       

st = pd.DataFrame(result)#create data frame 
st.to_csv(r'C:\Users\efthi\Desktop\results.csv', index=False)#insert data frame to csv       

This is supposed to be running in an even bigger dataset, which I think is more efficient to utilize the multiple cores of my pc

How can I implement it to use all 4 cores?
