Write a code for reading FASTA sequence with Bio.Fasta packag

Sure, here is a simple Python code snippet using the BioPython package to read a FASTA file:

from Bio import SeqIO

def read_fasta_file(file_path):
    for record in SeqIO.parse(file_path, "fasta"):
        print("ID: ", record.id)
        print("Sequence: ", record.seq)
        print("Length: ", len(record))

# Call the function with your fasta file path
read_fasta_file("your_file_path.fasta")

In this code:

1. We first import the necessary module SeqIO from the Bio package.
2. We define a function read_fasta_file that takes a file path as an argument.
3. Inside the function, we use SeqIO.parse to read the fasta file. This function returns an iterator giving SeqRecord objects.
4. For each SeqRecord, we print out its ID, sequence, and length.
5. Finally, we call the function with the path to your fasta file.

Please replace "your_file_path.fasta" with the path to your actual FASTA file.
