Why is Sage calling 1 a variable?
Consider
x = var('x')
f = 1/(x-3)
limit(f,x=3,dir='below')
UnboundLocalError: local variable 'l' referenced before assignment
1 Answer
Try with limit(f, x=3, dir='minus').
I think this is a (trivial) bug, thanks for reporting. The code in question is in lines 1228-1245 of calculus.py.
Edit: this is #23048.

I'm using preformat so I have no idea why the first two statements keep showing up on the same line, but they aren't
The error message is
local variable 'l' referenced before assignment. It's variablel(small cap L), not1. I have reported the issue on sage-dev.Thanks for reporting.
