請問各位大佬，我按照影片教學的方法輸入程式碼：

from selenium import webdriver
web = webdriver.Chrome()
web.get("https://www.dcard.tw/f")
search = web.find_element_by_name("query")
search.send_keys("博愛座")

然後運行之後就輸出這些：

/usr/local/bin/python3 "/Users/qiufuwei/Library/Mobile Documents/com~apple~CloudDocs/python/simpledriver.py"
qiufuwei@qiufuweideAir python % /usr/local/bin/python3 "/Users/qiufuwei/Library/Mobile Documents/com~apple~CloudDocs/python/simpledriver.py"

而且也不會按照我寫的找到搜尋框並輸入“博愛座”
請問我是哪裡寫錯了嗎，還請各位大佬指教謝謝

你要先下載webdriver，然後如果還有問題，指定webdriver的絕對路徑。

web = webdriver.Chrome("你上面下載的exe檔")

下載chromedriver的網址如下:
https://sites.google.com/chromium.org/driver/downloads?authuser=0
記得找跟自己chrome瀏覽器版本一致的chromedriver下載(裡面還有分不同作業系統)

解壓縮後，在程式碼裡指定chromedriver.exe的路徑，就可以正常跳出dcard視窗並在搜尋打上"博愛座"，下面是我測試時的檔案路徑。

from selenium import webdriver
web = webdriver.Chrome('chromedriver.exe') //這邊要改成chromedriver的路徑
web.get("https://www.dcard.tw/f")
search = web.find_element("name", "query")
search.send_keys("博愛座")
