Why is re.findall not being specific in finding triplet items in string. Python

Question

So I have four lines of code

seq= \'ATGGAAGTTGGATGAAAGTGGAGGTAAAGAGAAGACGTTTGA\'



OR_0 = re.findall(r\'ATG(?:...){9,}?(?:TAA|TAG|TGA)\',seq)  

Answer 1

Try this:

seq= 'ATGGAAGTTGGATGAAAGTGGAGGTAAAGAGAAGACGTTTGA'
OR_0 = re.findall(r'ATG(?:.{3})*?(?:TAA|TAG|TGA)',seq)
