Invalid syntax error using :=

[DrBwts]

Pthyon 3.8

I'm using the following code from the examples on the docs page,

import schemdraw
from schemdraw import logic

with schemdraw.Drawing() as d:
    d.config(unit=0.5)
    d += (S := logic.Xor().label('S', 'right'))
    d += logic.Line().left(d.unit*2).at(S.in1).idot().label('A', 'left')
    d += (B := logic.Line().left().at(S.in2).dot())
    d += logic.Line().left().label('B', 'left')
    d += logic.Line().down(d.unit*3).at(S.in1)
    d += (C := logic.And().right().anchor('in1').label('C', 'right'))
    d += logic.Wire('|-').at(B.end).to(C.in2)

This throws the folloiwng error,

  File "D:\Python codes\temp.py", line 11
    d += (S := logic.Xor().label('S', 'right'))
            ^
SyntaxError: invalid syntax

Any idea why this is happening?

I just tested it (Python 3.9.4, win 10, schemdraw 0.14) and works perfectly fine.
Seem's like you have issues with the walrus operator.
Are you sure you are using Python>3.8 (FYI https://docs.python.org/3/whatsnew/3.8.html)
Anyway, you can circumvent the issue by explicitly declaring de variables before adding it to the drawing :
S = logic.Xor().label('S', 'right')
d += S

Ahhhh yeah I was in the wrong environment. Thanks for the sanity check, Nic
