[Biopython] sff inot fasta and qual then trim

[Kiss, Csaba]

I am new to bio-python. I am trying to replace mothur with BioPython.
I hope that biopython is faster than mothur. All I want to do is this:

sffinfo(sff=sd11.fasta)
trim.seqs(fasta=sd11.fasta, qfile=sd11.qual, minlength = 50, maxhomop=8, qwindowsize=50, qwindowaverage =22)

Can someone help me to translate the two mothur statements above to biopython, please?
It would be greatly appreciated.
thanks
