Usage

To view the code for any program, use the print_program function:

from ngd.programs import print_program

# Print program 1 (DNA Manipulation)
print_program(1)

# Print program 2 (FASTA Reading)
print_program(2)

# Print program 3 (GenBank Operations)
print_program(3)

# And so on for programs 4-10...
