Python Reading

• Read the chapter entitled Lists from section "Lists" through section "Cloning Lists".

Key Ideas

• A list is an ordered collection of items that can be of any type, e.g. ["Joy and Beauty of Data", 2017].
• List creation
  • row_1 = ["Jerico", "Riley", "Anna", "Jessica"]
  • row_2 = ["Leah", "Nick", "Amber", "Cory"]
  • rows = [row_1, row_2]
• Determining List Length: len
• Accessing List Elements
  • row_1[1]
  • rows[1][2]
• List Membership: in and not in
• List Concatenation: +
• List Repetition: *
• List Slices
  • row_1[2:4]
  • row_1[:2]
  • row_1[2:]
• Lists are mutable (unlike Strings)
  • Replacement: row_1[0] = "Morgan"
  • Deletion: row_1[1:3] = []
  • Deletion: del(row_1[0])
  • Insertion: row_2[2:2] = ["Logan", "Daniel", "Dyllan"]
• List Aliasing: row_1 = row_2
• List Cloning: row_1 = row_2[:]
