python中的For循环x从文件中执行的次数

该脚本针对accounts.txt文件中存在的帐户数运行。无论accounts.txt文件中有多少个帐户，我都希望运行脚本x多次。所以我只需输入一个输入10，脚本应该只运行for循环10次。下面是我的代码

有人能帮我修复for循环或为for循环添加新的父循环吗

file = open('accounts.txt','r')

for line in file:
    credentials = line.split(";")
    username = credentials[0]
    password = credentials[1]
    comment = credentials[2]

    chromedriver = "/Users/Ali/Downloads/chromedriver"

    os.environ["webdriver.chrome.driver"] = chromedriver
   # driver = webdriver.Chrome(chromedriver)
    chrome_options = webdriver.ChromeOptions()
    chrome_options.add_argument("--mute-audio")

这应该起作用：

for count, line in enumerate(file):
    credentials = line.split(";")
    username = credentials[0]
    password = credentials[1]
    comment = credentials[2]

    chromedriver = "/Users/Ali/Downloads/chromedriver"

    os.environ["webdriver.chrome.driver"] = chromedriver
   # driver = webdriver.Chrome(chromedriver)
    chrome_options = webdriver.ChromeOptions()
    chrome_options.add_argument("--mute-audio")

    if count == 9: # count starts at 0
        break

将阅读内容放入函数中：

def run_loop():
    file_han = open('accounts.txt','r')
    file = file_han.read().split('/n') #you need to read and split the file w.r.t lines
    file_han.close()
    for line in file:
        credentials = line.split(";")
        username = credentials[0]
        password = credentials[1]
        comment = credentials[2]

        chromedriver = "/Users/Ali/Downloads/chromedriver"

        os.environ["webdriver.chrome.driver"] = chromedriver
        # driver = webdriver.Chrome(chromedriver)
        chrome_options = webdriver.ChromeOptions()
        chrome_options.add_argument("--mute-audio")

#Now loop the function over and over
i=0
while i =! input('Enter iterations no:'):
    run_loop()
    i=i+1

解决此问题的另一种方法是使用

itertools.islice（）

，它允许您从迭代器（例如文件指针）中选择所需的值：

import itertools

with open('accounts.txt', 'r') as file:
    wanted_lines = 10
    for line in itertools.islice(file, wanted_lines):
        credentials = line.split(";")
        username = credentials[0]
        password = credentials[1]
        comment = credentials[2]

        chromedriver = "/Users/Ali/Downloads/chromedriver"

        os.environ["webdriver.chrome.driver"] = chromedriver
       # driver = webdriver.Chrome(chromedriver)
        chrome_options = webdriver.ChromeOptions()
        chrome_options.add_argument("--mute-audio")

此外，在这里，我使用了带有open…结构的

来打开要读取的文件。这样做的好处是，文件将在到达
块的
末尾时自动关闭。
您可以使用
x=0
这样的变量，然后使用
而x<10:
作为循环，因为这将循环10次。请发布一个经过审查的帐户示例。txtUse以计算迭代次数，并在达到限制时停止具有myemail@gmail.com;密码；注释很好我修复了我的问题，只需要在它接受输入后将其转换为整数。。非常感谢。。
