Lies My Calculator and Computer Told Me [pdf]
What you've done here is tell SymPy to use extra precision for the intermediate (and final) output. This doesn't truly fix the problem of cancellation and loss of precision, but for many practical purposes it can postpone the problem long enough to give you a useful result.
Internally, SymPy uses mpmath (https://mpmath.org/) for representation of numbers to arbitrary precision. You could install and use the latter library directly, gaining extra precision without going through symbolic manipulation.
All that being said, it's still good practice to avoid loss of precision at the outset. Arbitrary-precision calculations are slow compared to hardware-native floating point operations. Using the example from mpmath's homepage in iPython:
In [1]: import mpmath as mp; import scipy as sp; import numpy as np -

Either use a fixed point system with enough precision (determined beforehand) or consider a library like https://mpmath.org.

Math with Significant Figures
Probably the most popular package for dealing with error propagation and arbitrary precision arithmetic in Python is mpmath, more specifically the mp.iv module. For more serious applications I'd take a look at MPFR and Arb, both in C. And there are tons of ball arithmetic and interval arithmetic libraries in Fortran.

Integrating an extremely oscillating function!
Elaborating on /u/lanemik: if you're forced to do everything numerically and aren't able to use rationals, you can also use multiple-precision arithmetic. It's significantly slower, but it's as precise as you need it to be. Note that numpy will happily work with other objects that define arithmetic operations. I haven't messed with scipy enough to know how it does things.
- were can i find advance ( hardest ) python projects with source code ?
