Python 3 - Formatting print commands

New to python and I'm trying to export some information from network devices and format it into a text file. I have the below code I'm running;

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)

I'm trying to change the output from looking like:

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

to:

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

Any ideas on how I'd go about this?

I'm assuming net_connect.send_command() returns a string with a trailing newline.

If that's correct,

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()

– i.e. strip()ing the outputs – should do the trick.

Use .strip() to remove the unwanted \n character in your output:

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
