How to retrieve instagram post data with Selenium

instagram_post_data.py

from selenium import webdriver

driver = webdriver.Chrome('../chromedriver')
driver.get('https://www.instagram.com/accounts/login/')

def get_post_description():
    description = driver.execute_script('''return document.getElementsByClassName('C4VMK')[0].getElementsByTagName('span')[0].innerText''')
    return description 

def get_post_date():
    date = driver.execute_script('''return document.getElementsByClassName('_1o9PC Nzb55')[0].getAttribute('datetime')''')
    return date

def get_total_likes():
    
    try:
        likes = driver.execute_script('''return document.getElementsByClassName('Nm9Fw')[0].lastElementChild.getElementsByTagName('span')[0].innerText''')
        likes = [i.split('\n')[0] for i in likes]
        likes = ', '.join(likes)
        
        return likes
    except:
        return 0

This will not work persistent since the class names change from time to time
