A file in fasta format is probably the most common way to store sequence information. The format is very simple: the name of each sequence is listed on a line beginning with a '>' (the sequence name is everything after the '>'), and the sequence associated with that name is listed on one or more lines after the name line. For a more detailed description, see http://www.ncbi.nlm.nih.gov/BLAST/fasta.shtml. For the examples below, program output will be shown for the following fasta-format file, called seqs. fa: human Fasta files: Write a program sortFasta.py that accepts a single command-line argument which is the name of a file in fasta format. First, it reads in the file of DNA sequences in fasta format and stores them in memory. Then, your program should re-print the sequences in fasta format to the screen, sorting the sequences by sequence name. Hint: a dictionary is a convenient data structure for holding the Example program usage
