No Sympy Two-sided Limits?

I can't get Sympy to handle two-sided limits. Running in a Jupyter notebook, Anaconda installation: from sympy import * x = symbols('x') limit(1/x,x,0) gives an answer of oo. F

Solution 1:

limit has a fourth argument, dir, which specifies a direction:

>>> limit(1/x, x, 0, '+')
oo
>>> limit(1/x, x, 0, '-')
-oo
>>> limit(1/x, x, 0)
oo

The default is from the right. Bidirectional limits are not directly implemented yet, but you can easily check both directions.

Solution 2:

Two sided limits are now directly implemented.

>>> limit(1/x**2, x, 0, '+-')
oo
