Question

[Heloooooooo]

can someone solve this for me?

Write a function 'kmers' that count the kmers of length 3. It should get a DNA sequence and return a dictionary with the substrings of length 3 as keys and the number of occurrences in the sequence as value. Example:

kmers('CGCTAACGCAC') = {'AAC': 1,

'ACG': 1,

'CAC': 1,

'CGC': 2,

'CTA': 1,

'GCA': 1,

'GCT': 1,

'TAA': 1}
