Reaching in
  • ▸Make one: genes = ["BRCA1", "TP53", "EGFR"]
  • ▸Index by position: genes[0] (first), genes[-1] (last)
  • ▸Slice a range: genes[1:3] — end not included
Changing & summarising
  • ▸Grow: genes.append("MYC") / genes + more
  • ▸Edit by position: genes[1] = "KRAS" / del genes[0]
  • ▸Numbers: sum(values) / len(values) → the mean
