使用Python+selenium获取tag_element标签输入内容出现错误

今天第一次使用Python写脚本，目的：登陆www.zealer.com，在搜索框搜索“小米8”
编辑python代码：

from selenium import webdriver
from time import sleep

driver=webdriver.Chrome()

driver.get("http://www.zealer.com")
#driver.maximize_window()     
driver.find_element_by_tag_name("input").send_keys("小米8")
sleep(3)
driver.quit()

当时没用到是网页窗口最大化显示：driver.maximize_window()
导致结果：

同时Pycharm开始报错：

"C:\Program Files\Python3\python.exe" E:/python_script/Webdriver/Find_Element/By_tagName.py
Traceback (most recent call last):

反复检查代码，百思不得其解。
最后试一下窗口最大化显示：driver.maximize_window()

代码运行成功。

分析原因：selenium.common.exceptions.ElementNotVisibleException: Message: element not interactable
提示元素不可交互，说明窗口化没有显示到搜索框，代码无法继续运行?
