 We need to develop some **functions** to create sequences for **testing** the Seq objects. For instance, the function **generate_seqs(pattern, number)**, that has two parameters, will create a **list** with the provided _number_ of sequences. All sequences are created from the provided **pattern**. This pattern is a string of one or more valid bases. The first sequence of the list will be the pattern, the second will consist in the pattern repeated twice, in the third, the pattern will be repeated three times, and so on.
