I am still learning python and I wrote script that is logging to cisco devices and run command and write to csv file and send as email attachment but when open the file on my Windows machine it has unreadable symbols:
enter image description here



If router is not reachable just writes file saying device down and it shows 0 as empty file in Unix but on Windows i see this:
enter image description here



Below is the script:



> def ssh_conn():
> user = 'xxxxxxx'
> passwd = 'xxxxxx'
> file2 = ("hostfile")
> hosts = open(file2,'r')
> for host in hosts:
> try:
> hostIp = host.split(',')[1]
> device = host.split(',')[0]
> session = paramiko.SSHClient()
> session.set_missing_host_key_policy(paramiko.AutoAddPolicy())
> session.connect(hostIp.strip(), username = user, password = passwd)
> connection = session.invoke_shell()
> connection.send("terminal width 0n")
> connection.send("sh archive config differences nvram:startup-config system:running-config | exc !|Diffn")
> time.sleep(1)
> output = connection.recv(5000)
> f = open(device +".csv", "w")
> f.write(output+'n')
> f.close()
> except:
> #f1 =codecs.open(device +"-DOWN.csv", "w", encoding="utf_16")
> f1 = open(device +"-DOWN.csv", "w")
> f1.close()
> pass
> files = glob.glob('*.csv')
> for file in files:
> if os.stat(file).st_size > 0:
> try:
> df=pd.read_csv(file,skiprows = 1).dropna()
> if len(df) <=2:
> os.remove(file)
> elif len(df) > 2:
> df=pd.read_csv(file, skiprows = 1, header=True).dropna()
> df.to_csv(file, index=False)
> else:
> print 'Empty File..passing'
> pass
> except ValueError:
> print 'Modified file'
> pass ssh_conn() print "Completed!"


I have tried using some encoders but same. Also was trying to write to txt file is the same. Hope you can provide a hint.
