Solving Partial Differential equation in Python

[Calvin]

Greetings,
	Did anyone have the experience in solving a PDE numerically in Python. 
The PDE is a Euler-Lagrange equation. In fact it is a simulation of LCD 
modeling. I search the web and find many libraries like Numeric Python. 
But I cannot find any library aim at solving PDE. So I think I have to 
design my own Algorithm. Could anyone help me.
