python中的多个else条件

我有一个python脚本，它将读取文件中的每个IP，并使用密码在该IP上安装代理，有5-6个密码，如果一个密码不起作用，它应该逐个尝试使用其他所有密码。 这是我的剧本：

##Reading values from SucessfullIp.txt
with open('/root/nix_bsd_mac_inventory-master/SucessfullIp.txt') as f:
    ips = set(line.rstrip() for line in f)

##Reading Unique Ip's values 
with open("/root/nix_bsd_mac_inventory-master/Unique.txt") as fp:
        for line in fp:
                line = line.rstrip()
                ## Comparing unique ip's if ip is already has scanned
                if line in ips:
                        print('{}: Ip is Already Tried: '.format(line))
                else:
                ##Creating inventory.cfg file on the fly for each ip
                        f3 = open("/root/nix_bsd_mac_inventory-master/inventory.cfg", "w")
                        print "Processing Ip: " + line
                        f3.write("[device42_access]"  + "\n" +
                        "base_url = https://1.8.0.3"  + "\n" +
                        "username = uname"  + "\n" +
                        "secret = abcd"  + "\n" +
                        "[discover]"  + "\n" +
                        "cpu= true"  + "\n" +
                        "hardware = true"  + "\n" +
                        "memory = true"  + "\n" +
                        "[access]"+ "\n" +
                        "credentials = username:passowrd1" + "\n" + ##here we are giving credentials and we have 5-6 passwords
                        f3.close()
                        p = subprocess.Popen(["./d42_linux_autodisc_v620"], stdout=subprocess.PIPE) ##This script will require inventory.cfg file created above
                        p1 = str(p.communicate())
                        if '1 devices were successfully added/updated' in p1:
                                print ('Sucessfull Completed Ip: ' +line)
                                f6 = open("/root/nix_bsd_mac_inventory-master/SucessfullIp.txt","a")
                                f6.write("\n"+line)
                                f6.close()
                        else:
                                print "Unsuccessfull"
                            ##here want it to check it with other passwords as well

您可以使用for循环和单个else执行此操作：

for password in list_of_password:
    ...
    "credentials = username:" + password + "\n"
    ...
    if '1 devices were successfully added/updated' in p1:
        ...
        break
else:
    print "Unsuccessfull"

---

你应该迭代你的密码列表，如果成功的话，你应该跳出这个循环

以下代码段中存在语法错误：

"credentials = username:passowrd1" + "\n" + 

这不应以

+

结尾，因为您没有将任何其他内容连接到字符串

这将有助于您查找可以与循环一起使用的内容，正如我在答案中使用的那样

我已经删除了你的所有评论，并添加了我自己的评论来解释逻辑

with open("/root/nix_bsd_mac_inventory-master/Unique.txt") as fp:
    for line in fp:
        line = line.rstrip()
        if line in ips:
            print('{}: Ip is Already Tried: '.format(line))
            continue  # Continue means it will skip to the next password
        passwords = ['password1', 'password2', 'password3']
        for password in passwords:
            f3 = open("/root/nix_bsd_mac_inventory-master/inventory.cfg",
                      "w")
            print "Processing Ip: " + line
            f3.write("[device42_access]" + "\n" +
                     "base_url = https://1.8.0.3" + "\n" +
                     "username = uname" + "\n" +
                     "secret = abcd" + "\n" +

                     "memory = true" + "\n" +
                     "[access]" + "\n" +
                     "credentials = username:" + password + "\n"  # Fixed typo here
            f3.close()
            p = subprocess.Popen(["./d42_linux_autodisc_v620"],
                                 stdout=subprocess.PIPE)
            p1 = str(p.communicate())
            if '1 devices were successfully added/updated' in p1:
                print('Sucessfull Completed Ip: ' + line)
                f6 = open("/root/nix_bsd_mac_inventory-master/SucessfullIp.txt", "a")
                f6.write("\n" + line)
                f6.close()
                break  # If successful it breaks, so don't need an else
            print "Password %s Unsuccessfull" % password
        else:
            # This happens when there are no more passwords to attempt
            print "No passwords were successful"

在你的问题中没有问题。很抱歉，我如何才能包含多个其他密码来运行5-6个密码的脚本如果一个密码不起作用，它应该为其他密码运行，最后一个密码应该为所有密码运行。你可能希望对所有密码执行

循环，如果任何密码成功，你将
中断
else
您可能希望打印字符串
“Unsuccessful”
。for else可能是一个好方法，但请将您的行固定在
credential=…
list\u密码是数组？@AkashSarpate在Python中我们没有数组，只有列表后面是else条件：print（“{}:Ip已尝试：”。format（line））在脚本中，您在继续之后没有包含其他内容。请检查我上面的脚本，并确认如果ips:print（“{}:Ip已尝试：”.format（line））#继续其他：对于密码中的密码：f3=打开(“/root/nix\u bsd\u mac\u inventory-master/inventory.cfg”，“w”）print”使用第一个密码检查：“print”处理Ip:“+lineI我已根据您的建议进行了更改，出现错误：[root@10nix_bsd_mac_inventory-master]#python s2.py文件“s2.py“，密码中密码的第43行：^IndentationError:应为缩进块您没有正确复制它。这是有关缩进的语法错误。您应该修复缩进。缩进错误已修复，但由于其他条件，它正在按预期运行，您能检查我的上述脚本并给出您的输入吗
