Writing to file in a specific folder

[evapa8f]

Having trouble writing to a file in a specific directory. I'm using a loop to capture info from multiple devices so the actual filename is represented as a the variable "file"

 file = (hostname + '.txt')
 file = file.lstrip("\r\n")
 s = open('\\home\\verizon\\backups\\Cisco\\'%file ,'w')
 s.write(output)
 s.close()

Please, use proper tags when post code, traceback, output, etc. This time I have added tags for you.
See BBcode help for more info.

s = open(f'/home/verizon/backups/Cisco/{file}' ,'w')

[evapa8f]

s = open(f'/home/verizon/backups/Cisco/{file}' ,'w')

getting this error

Error:

  File "iosbackup.py", line 73
    s = open(f'/home/verizon/backups/Cisco/{file}' , 'w')

Carrot belongs under the second quote (after {file})

F-strings (which this example uses) were introduced in python 3.6. You'll get a syntax error in earlier versions. What version are you using? Can you use a more recent copy?

[Axel_Erfurt]

For older version use

s = open("%s%s" % ('/home/verizon/backups/Cisco/', file), 'w')

Should use os.path or pathlib.
