将结果转储到与变量名称相同的文本文件中

Question

I'm trying to write a code using netmiko that will execute few Show commands and save the results into text file with the name of variable (which is IP here).

For example if I insert IP 8.8.8.8 I want the results to be save into a text file with the name 8.8.8.8. Any ideas?

Answer 1

The problem is that print returns None , and you're setting pre_r equal to that print call's return value:

pre_r = print(connection.send_command(command))

Instead, set pre_r equal to the data, and print that instead:

for command in commands:
    pre_r = connection.send_command(command)
    print(pre_r)

with open(SwIp, 'wb') as f:
    f.write(pre_r)

You also may want to move that for loop inside the with statement:

with open(SwIp, 'wb') as f:
    f.writelines([connection.send_command(cmd) for cmd in commands])

Answer 2

Since the SwIp variable appears to contain the IP address (as a string), you can do it by slightly changing how you open() the file.

with open(SwIp, 'wb') as f:
    f.write(str(pre_r)+'\n')

Note I added a trailing newline to the data written to the file and removed the unnecessary f.close() in your code (the with will do that for you automatically).
