I have this enviroment variable: VAR=C:\Users\User but how can I prevent python giving this "SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape error when I try:

import os
os.environ["VAR"]

without needing to change the variable in Command line

Reset to default

Add r to let compiler knows it's a raw string.

r'{}'.format(os.environ["VAR"]))

However, your code works on myside without any changes.

The unicode error comes from the "\U". So you can also change your

VAR=C:\Users\User

to

VAR=C:\\Users\\User

so that Python recognizes the dashes as literal dashes.

is this without changing the variable? no
Sorry, did not read the last part. But it may help you to know where the SyntaxError is coming from.

Maybe the reason are the dashs. Did you try:

Try VAR=C:/Users/User
