DNA Complement 2

The data for this problem is no longer available.

Download the file sequence_data_complete.txt from the website. This file consists of three columns separate by commas: 1) A sequence ID (like the primary keys we’ve using in our database work); 2) The length of the sequence; and 3) The sequence itself as a string. Import the file into a Numpy array (using genfromtxt). Use a for loop to print the following statement for each row of the datafile:

The complement of Sequence ID sequence_id is complement. This sequence is sequence_length bases long.

Use the complement function you wrote for the DNA Complement 1 problem to determine the value of complement. Bold words indicate that you should substitute the actual value in place of the word so that an example sentence looks like:

The complement of Sequence ID 20 is taaccggtgga. This sequence is 11 bases long.
