I am looking forward to hearing feedback from the SymPy commuity on this
project.
Thank you very much!

In addition:
[image: error.png]
I wonder whether someone has the similar problems. Because I remember I
have no such error before I reinstall the anaconda and sympy.
So I wonder is this because of the update?
Thank you very much!

hey, all the friends in the group,
I have a question, which I don't know how to solve it.
StringA='DP(OAMHolo(BS(OAMHolo(OAMHolo(OAMHolo(OAMHolo(LI(XXX,a,d),d,5),e,3),b,5),c,3),a,d),c,9),a)'
fundict={'BS':BS,'LI':LI,'Reflection':Reflection,'OAMHolo':OAMHolo,'DP':DP}

hey,
I wander whether one has occurred such problem:
I define a initial state:
state=a[1]*b[0]*c[0]*d[0]*1j+a[1]*b[0]*c[0]*d[0] + a[2]*b[1]*c[1]*d[1]
# for some reason I have to do such decomposition
datalist=state.as_coefficients_dict()
I can get:
{
]*d[4]+a[1]**2*b[3]*c[1]*d[4]+a[1]*b[2]**2*c[3]+b[2]*c[3]+...
I only want to take the cases for terms containing b[xxx]*c[xxx]*d[xxx],
other cases are all becoming to 0.
Do you have any ideas? I thought about match, but seems wrong.
Thank you very much!
Best regards,

hey, everyone.
hello, I recently played with sympy for comparing with wolfram language. I
wonder whether there is a simple way to do the _ (blank) as mathematica do.
Here is a link:
