Description
Hecke algebra basis is not implemented. here is how one can reproduce it:
sage: M=ModularSymbols(431,2,1) sage: C=M.cuspidal_submodule() sage: TT=C.hecke_algebra() sage: TT.basis() --------------------------------------------------------------------------- <type 'exceptions.NotImplementedError'> Traceback (most recent call last) /home/syazdani/sage-2.11.alpha1/<ipython console> in <module>() /home/syazdani/sage/local/lib/python2.5/site-packages/sage/modular/hecke/algebra.py in basis(self) 145 146 def basis(self): --> 147 raise NotImplementedError 148 149 def discriminant(self): <type 'exceptions.NotImplementedError'>:

This works for me on 5.5.rc0
:
sage: M = ModularSymbols(431,2,1) sage: C = M.cuspidal_submodule() sage: TT = C.hecke_algebra() sage: TT.basis() [Hecke operator on Modular Symbols subspace of dimension 36 of Modular Symbols space of dimension 37 for Gamma_0(431) of weight 2 with sign 1 over Rational Field defined by: ... 36 x 36 dense matrix over Rational Field]

It also works for me in 5.7.beta4 so I'm giving the wontfix
a positive review.
