Blynk.virtualWrite(V0, 0) syntax error or 'Blynk' isn't defined

Need Help With My Project
1

I read all the previous posts on this subject (Blynk.virtualWrite) and cannot find a way to solve my problem.

I am running a microPython sketch and everything works well with sliders and switches using the web-based console or the android app.
When I add this line of code to my sketch, I get an error message
Blynk.virtualWrite(V0, 0)
“SyntaxError: invalid syntax”

When I change it to
@Blynk.virtualWrite(V0, 0)
I get the error message
NameError: name ‘Blynk’ isn’t defined

When I change it to
@blynk.virtualWrite(V0, 0)
I get the error message
AttributeError: ‘Blynk’ object has no attribute ‘virtualWrite’

My system
Raspberry Pi Pico W,
Thonny micropython IDE
Blynk for Python v1.0.0 (rp2)

The relevant portion of my code that produces an error when I add the virtualWrite command is:

blynk = BlynkLib.Blynk(BLYNK_AUTH)
@blynk.on("connected")
def blynk_connected(ping):
    print('Blynk ready. Ping:', ping, 'ms')
# Register virtual pin handler
@blynk.on("V0") #virtual pin V0               
@Blynk.virtualWrite(V0, 0)   # problem command

Assuming you’re using the v1.0.0 library (the only one that works correctly with Blynk IoT) then the syntax used in the examples is:

blynk.virtual_write(vPin, value)
