Selenium big struggle

[Troop]

from selenium import webdriver
from time import sleep

class scrollDown:

    def __init__(self, username, passWord):
        self.driver = webdriver.Chrome()
        self.driver.get("https://instagram.com")
        self.username = username
        self.passWord = passWord
        sleep(2)
        self.driver.find_element_by_xpath("/html/body/div[1]/section/main/article/div[2]/div[1]/div/form/div[2]/div/label/input")\
            .send_keys(username)
        self.driver.find_element_by_xpath("/html/body/div[1]/section/main/article/div[2]/div[1]/div/form/div[3]/div/label/input")\
            .send_keys(passWord)
        self.driver.find_element_by_xpath("/html/body/div[1]/section/main/article/div[2]/div[1]/div/form/div[4]/button")\
            .click()
        sleep(5)

        #REMOVE NOTIFICATIONS WINDOW
        self.driver.find_element_by_xpath("/html/body/div[4]/div/div/div[3]/button[2]").click()
        sleep(3)
        print("Logged in")

        for i in range(100):
             self.driver.execute_script("window.scrollBy(0, 200)")
             sleep(1)
             print(str(i)+"%")

         #ALTERNATIVE
        headers = self.driver.find_elements_by_tag_name('header')
        for users in headers:
            pictureLocation = self.driver.find_element_by_class_name('O4GlU').get_attribute("href")
            stringLocation = str(pictureLocation)
            if "London" in stringLocation or "london" in stringLocation:
                nameLink = users.find_elements_by_tag_name('a')
                print(nameLink)
