Python 3 - 格式化打印命令

Question

python 新手，我正在嘗試從網絡設備導出一些信息並將其格式化為文本文件。 我正在運行以下代碼；

for device in (LD6AGGSW01 , LD6AGGSW02 ):
    net_connect = ConnectHandler(**device)
    output = net_connect.send_command('show hostname')
    pickle.dump(output, open("hostname.p", "wb"))
    output = net_connect.send_command('sh ver | i NXOS | i image |i file |i is:')
    output = output.strip()
    pickle.dump(output, open("IOSimage.p", "wb"))
    output = pickle.load(open("hostname.p","rb"))
    print('Hostname: ' + output)
    output = pickle.load(open("IOSimage.p","rb"))
    print(output)

我試圖改變輸出看起來像：

Hostname: LD6-AGG-SW01 

NXOS image file is: bootflash:///nxos.7.0.3.I3.1.bin
Hostname: LD6-AGG-SW02 

NXOS image file is: bootflash:///nxos.7.0.3.I3.1.bin

到：

Hostname: LD6-AGG-SW01 
NXOS image file is: bootflash:///nxos.7.0.3.I3.1.bin

Hostname: LD6-AGG-SW02 
NXOS image file is: bootflash:///nxos.7.0.3.I3.1.bin

關於我將如何處理這件事的任何想法？

Answer 1

我假設net_connect.send_command()返回一個帶有尾隨換行符的字符串。

如果這是正確的，

for device in (LD6AGGSW01 , LD6AGGSW02 ):
    net_connect = ConnectHandler(**device)
    hostname = net_connect.send_command('show hostname').strip()
    ios_image = net_connect.send_command('sh ver | i NXOS | i image |i file |i is:').strip()
    print('Hostname:', hostname)
    print('Image:', ios_image)
    print()

– 即strip()輸出 – 應該可以解決問題。

使用.strip()刪除輸出中不需要的\\n字符：

for device in (LD6AGGSW01 , LD6AGGSW02 ):
    net_connect = ConnectHandler(**device)
    output = net_connect.send_command('show hostname')
    pickle.dump(output, open("hostname.p", "wb"))
    output = net_connect.send_command('sh ver | i NXOS | i image |i file |i is:')
    output = output.strip()
    pickle.dump(output, open("IOSimage.p", "wb"))
    output = pickle.load(open("hostname.p","rb"))
    output = output.strip()    # Strip output
    print('Hostname: ' + output)
    output = pickle.load(open("IOSimage.p","rb"))
    output = output.strip()   # Strip output
    print(output)
    print()    # Call print function to insert extra line
