In Python, am being asked to make a dictionary from whats in the string (FASTA Sequence), with the alphanumeric part (identifier) being the key and the letters (sequence) being the value. I was first asked to make a list of identifiers, so split the lines so I could isolate them. I now have no idea how to proceed in joining the elements of the sequence WITHOUT losing any part of the sequence or identifier. The sequence is not imported, it was posted as is by my professor, so please no suggestions about changing that. Can anyone help figure out what I should do? However, it should be EXTREMELY simple because I am only a couple weeks into taking a python course for school. I have tried using the join command in a for loop, but because I need it to update the list I am working with, I believe it doesn't work, as there is no output. However there is no error message either. I have tried replacing the new lines with nothing to join the elements that compose the sequence, but when it is time to separate it from the identifier, I am losing information (particularly the 1 and the first letter of sequence). I also have several new line characters within the sequence I need to get rid of as wellI cannot alter the original sequence in any way. I have attached my code but do not have anything currently for the task I am asking about, as I have had to start over.
