Python help with module function return dictionary

[Larz60+]

OK,

This should do the trick. It's not the most efficient code, but you can clean it up. It works, that's the important thing.

def read_fasta(filename=None):
    table_dict = {}
    update_dict = False
    if filename is not None:
        name = ''
        value = ''
        with open(filename, 'r') as f:
            for line in f.readlines():
                line = line.strip()

                if line[0] == ">":
                    if update_dict:
                        table_dict[name] = value
                        value = ''
                    name = line[1:]
                else:
                    update_dict = True
                    if len(line):
                        value += line

            if len(value):
                table_dict[name] = value

        print(table_dict)


if __name__ == '__main__':
    read_fasta('Ecoli.prot.fasta')
