i have a dictionary file, in which protein name is key and its sequence is value. i just want to retrieve all the protein sequences (values) not the keys in the same order as the keys are. Thank you. it is simple explanation, we can communicate further details.
Who wrote this script? And are you sure expasy allow this?
Anyway requests.post does not seem to work.
It can easily be done with biopython, but the problem in the script is not iteration but the query. The task you want to do can be done in seconds by single line command with emboss. No need for this complicated script. The main problem of the script was it was not successful with submitting query and parsing the results.
# biopython option
from Bio import SeqIO
filename = "protein_seq.fa"
for record in SeqIO.parse(filename, 'fasta'):
print(record.id)
# emboss option
iep -sequence protein_seq.fa -outfile result.iep -graph pdf -plot
pepstats -sequence protein_seq.fa -outfile results.pepstats
