Loops

Improve Your Code

This is a follow up to String Data.

A colleague has produced a file with one DNA sequence on each line. So far you’ve been manually extracting each DNA sequence and calculating it’s GC content, which as worked OK with five sequences, but isn’t going to work very well when the sequencer really gets going and you have to handle 100s-1000s of sequences.

Use a for loop and your function from String Data to calculate the GC content of each sequence and print them out. The function should work on a single sequence at a time and the for loop should repeatedly call the function and print out the result.
