Issues with substitution
I have a list L = [a13 == a10, a14 == a11, a15 == a12, a16 == a7, a17 == a8, a18 == a9]
I then have a running through a loop giving it these values
a = 1
a = 2a15a16 + 2a13a17 + 2a13a18 +1849
etc
I have
print(a)
a.subs(L)
print(a)
and it indicates no change, but I would of thought/ expected substitution to of taken place. Maybe I am being idiot, but please tell me where. I also posted this on stack overflow, sorry if I am not meant to post on both.
Thanks.
