Counting Repeated Str In Dna Pset6 Cs50

Currently working on CS50. I tried to count STR in file DNA Sequences but it always overcount. I mean, for example: how much 'AGATC' in file DNA repeat consecutively. This code is

Solution 1:

The for loop is wrong, it will keep counting the sequences even if they are already found earlier in the loop. I think you want to instead loop over the str_sequences.

Something like:

seq_list = []

for STR in str_sequences:
    groups = re.findall(rf'(?:{STR})+', dna)
    iflen(groups) == 0:
        seq_list.append('0')
    else:
        seq_list.append(str(max(map(lambda x: len(x)//len(STR), groups))))

print(seq_list)

Also, there are many posts on this problem. Maybe, you can examine some of them to finish your program.
