8. Python data structure List indexed a= [1,3,a,6,8,9] sliced
a[2],a[1:3],a[-1],a[-3:]a[:] concatenation a+[3,4,6] append
a.append(18) mutable a[1]=100 len len(a) Tuple Immutable t = 12345,
54321, hello! t[1]=22222 caution t=() type(t)->tuple, t=(1)
type(t)->int, tips: add comma Dict Python builtin dictionary, or
called map(key-value), quick search names = ['Michael', 'Bob',
Tracy'] scores = [95, 75, 85] , d = {'Michael': 95, 'Bob': 75,
'Tracy': 85} d[Bob]
