Header :is_valid_sequence:
Type Contarct :(str) -> bool
There are at least 2 ways to approach this. One way is to can count the number of characters that are not nucleotides and then at the end check whether there were more than zero. Another way is to use a Boolean variable that represents whether you have found a non-nucleotide character; it would start off as True and would be set to False if you found something that wasn't an 'A', 'T', 'C' or 'G'.
You should construct examples that contain only 'A's, 'T's, 'C's and 'G's, and you should also create examples that contain other characters. Lowercase characters are not valid.
