Hello, I have a similar question regarding Fasta module in Biopython. I am using disembl predictor Disembl.py) for protein disorder and I have a mistake ImportError: cannot import name Fasta. I read an answer in "Fasta module in Python/Biopython" record - to change Fasta with SeqIO but since I don't know Python, I didn't succeed to change the script. The problem is in the following two lines:

parser = Fasta.RecordParser()
iterator = Fasta.Iterator(db,parser)

which functions should I use instead?

and later, in line:

cur_record = iterator.next()

what to use instead of this? I tried to do the same as in suggested in "Fasta module in Python/Biopython" () but it works only once..
