正在将 python 字符串输出导出到记事本

Question

我正在尝试将第 19 行和第 20 行的字符串输出导出到记事本。

代码部分，第 1-21 行

1    import ipaddress
2    import socket
3    import sys
4    import os
5    
6    #networx prefix calc
7    def f1():
8        try:
9            network = input('please input network address with the prefix: ')
10           network = ipaddress.ip_network(network)
11           print(network)
12   
13       except ValueError:
14           print('That is not a network address')
15   
16       iplist= list(ipaddress.ip_network(network).hosts())
17       for i in range(10,len(iplist),2):
18           print(iplist[i])
19   
20       notepad1 = open('oddnetworks.txt','w')
21       notepad1.write(iplist)

这是我的输出，它是一系列奇数 IP 地址。请向下滚动到输出的底部以查看错误。

我收到的错误是，TypeError：write() 参数必须是 str，而不是列表我不知道如何将第 21 行转换为字符串。

输出

我想要这个程序，将奇数主机 IP 地址的输出保存到记事本文件中。

如有任何帮助，我们将不胜感激:)

用于测试的完整代码

import ipaddress
import socket
import sys
import os

#networx prefix calc
def f1():
    try:
        network = input('please input network address with the prefix: ')
        network = ipaddress.ip_network(network)
        print(network)

    except ValueError:
        print('That is not a network address')

    iplist= list(ipaddress.ip_network(network).hosts())
    for i in range(10,len(iplist),2):
        print(iplist[i])

    notepad1 = open('oddnetworks.txt','w')
    notepad1.write(iplist)



#port scan

Answer 1

如错误所述，您无法将列表写入文本文件。您必须遍历列表并逐行写入文本文件。把notepad1.write(iplist)改成

for ip in iplist:
    notepad1.write(f"{ip}\n")

Answer 2

您可以像这样在 for 循环中写入文件

iplist= list(ipaddress.ip_network(network).hosts())
notepad1 = open('oddnetworks.txt','w')
for i in range(10,len(iplist),2):
   print(iplist[I])
   notepad1.write(iplist)

# Don't forget to close!
notepad1.close()

Answer 3

您不需要自己编写显式循环代码。 print() 可以为您处理：

with open('oddnetworks.txt','w') as notepad1:
    print(*iplist, file=notepad1, sep='\n')

这使用 * 解压列表，将列表中的每个项目作为单独的参数传递给 print()。输出文件使用 file 设置，每一项用新行分隔。

另请注意使用 with 来打开文件以确保它被关闭。

Answer 4

我已经解决了，感谢您的回复。我会用本站用户提供的代码进行实验，让我的程序变得更好。

但我可以使用 str(iplist)) 输出到记事本

例如：

>  notepad1 = open('oddnetworks.txt','w')
>     notepad1.write(str(iplist))
