In Python, how do I check if a variable exists? [duplicate]

Question

If "x" exists, then print "x exists".

I ask this because I always get this error:

UnboundLocalError at /settings/
local variable 'avatarlink' referenced before assignment

Answer 1

Why do you need to know? If the code breaks because of this, it's probably because the code is wrong anyway and needs to be fixed.

That said, try checking if 'x' in locals() or if 'x' in globals(), as appropriate to where you're expecting it to be.
