'str'对象不可调用，但代码中没有变量 str

Question

我是Python和这个网站的新手。我想知道有没有人能帮忙。我有这段代码，但我只得到下面的错误。我在互联网上搜索，但我没有一个名为str的变量。谢谢你的帮助。

<标题>代码

from selenium import webdriver
from selenium.webdriver.common.by import By
username = "***"
password = "***"
driver = webdriver.Firefox()
driver.get("***")
driver.find_element(By.NAME("_username")).send_keys(username)

<标题>错误

Traceback (most recent call last):
File "/home/deniz/PycharmProjects/pythonProject/main.py", line 10, in <module>
driver.find_element(By.NAME("_username")).send_keys(username)
TypeError: 'str' object is not callable
Process finished with exit code 1

Answer 1

(By.NAME, "_username")not(By.NAME("_username"))

from selenium import webdriver
from selenium.webdriver.common.by import By
username = "***"
password = "***"
driver = webdriver.Firefox()
driver.get("***")
driver.find_element(By.NAME, "_username").send_keys(username)
