| + | 1) Your code will likely have a nested for loop. Use the length of the nested list within the matrix (''len(matrix[0])'') for the number of iterations in the outer for loop.\\ | ||

| + | \\ | ||
| + | 3) Append each element from the original nested lists within the matrix (''matrix[n][i]'', where n and i are the two iteration variables in the for loops - but which order?) to a new list within the nested for loop and then append the new list to a second new list in the outer for loop. | ||

| + | 1) Your first for loop should loop through the fastq file creating a dictionary with the sequence lines (''if (line_number + 3) % 4 == 1'') as the keys and the numbers of times each sequence appears as the values. You can increment the values using get (''fastq_dictionary[sequence] = fastq_dictionary.get(sequence, 0) + 1'').\\ | ||
| + | \\ | ||
| + | 2) The second for loop should loop through the fasta file and retrieve the number of reads for each sequence and should write the miRNA name and reads to a new file (''outfile.write(mirna_name[1:] + '\t' + str(fastq_dictionary.get(line, 0)) + '\n')''). | ||
