TypeError: descriptor 'readlines' of 'file' object needs an argument

Question

我每次运行都会收到这个错误，有人可以帮我吗

我想获取 url 并从我的 urls 列表中使用它，它在文本文件中 sewa.txt

那是代码

#encoding: utf-8
import random  
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import WebDriverWait # available since 2.4.0
from selenium.webdriver.support import expected_conditions as EC
import time

usr = ('')
pwd = ('')
poo =unicode ("","utf-8")
driver = webdriver.Firefox()
# or you can use Chrome(executable_path="/usr/bin/chromedriver")
driver.get('https://m.facebook.com/groups/192674874113111/')
assert "Facebook" in driver.title
elem = driver.find_element_by_name("email")
elem.send_keys(usr)
elem = driver.find_element_by_name("pass")
elem.send_keys(pwd)
elem.send_keys(Keys.RETURN)
time.sleep(22)
File=open('/home/sharkawey/Desktop/sewa','r');
for line in file.readlines():
    driver.get(line)
    elem = driver.find_element_by_name("lgc_view_photo")
    elem.send_keys(Keys.RETURN)
    time.sleep(15)
    driver.find_element_by_name("file1").send_keys("/media/sharkawey/THE HELL/2.jpg")

    elem = driver.find_element_by_name("xc_message")
    elem.send_keys(poo)
    elem = driver.find_element_by_name("photo_upload")
    elem.send_keys(Keys.RETURN)

那是错误

TypeError: descriptor 'readlines' of 'file' object needs an argument

Answer 1

你需要用到这个，

for line in File.readlines():

因为您声明的文件对象是 File 而不是 file 。 Python是一种区分大小写的语言，在引用变量时需要小心。

或

或者您可以使用 for line in File:，因为文件对象本身就是一个迭代器。
