Question

I want to store in a variable this path APPDATA%/Roaming/FileZilla/sitemanager.xml .

When i use:

file = "C:/Users/MyPC/AppData/Roaming/FileZilla/sitemanager.xml"

it works, but when i use:

file = "%APPDATA%/Roaming/FileZilla/sitemanager.xml"

the file cannot be stored and i cant send via paramiko.

Anyone helps?

Answer 1

You can retrieve the env variable with getenv function from os module. You can also use Path to easily manipulate paths.

import os
import pathlib

appdata = pathlib.Path(os.getenv('APPDATA'))
xmlfile = appdata / 'FileZilla' / 'sitemanager.xml'

Answer 2

You can use os.path.expandvars to expand environment variables in a string. On Windows, $ and % forms are accepted.

import os
file = os.path.expandvars("%APPDATA%/Roaming/FileZilla/sitemanager.xml")

(Note the leading %)
