Twitter upload issues using Twython - Syntax error - Invalid Token

I keep getting an Invalid Token error when I run the following .py.

What I'm trying to do it a simple photo booth upload to Twitter. When you press the button, it will take a pic, then upload it.

The tokens have been replaced with XXXX. They are correct.

I can't seem to correct the syntax error.

Any thoughts?

I don't know if this fixes things entirely but part of your problem is with the 04 you have in GPIO.setup(04, GPIO.IN), if (GPIO.input(04)):

You cannot use 0 before numbers in Python. For example:

a = 04

returns:

SyntaxError: invalid token

All you can do is to convert 04 to a string or remove the 0 entirely from your code.

Please see SyntaxError invalid token
