- list is as its name idicated, a list of values
- tuple is similar to list, but its value is not mutatable, you can re-assign the whole tuple
- set is a list with no duplication in values
- dictionary is a "list" of key: value pairs
syntax | value | notice |
---|---|---|
a = [1,2,3,4,5,6] | 1,2,3,4,5,6 | |
b = (1,2,3,4,5,6) | 1,2,3,4,5,6 | element inside tuple is not mutatable, but you can re-assign whole tuple |
c = {1,1,2,2,3,3,4,4,5,5,6,6} | 1,2,3,4,5,6 | no duplications of elements inside a set |
d = {"a":1, "b":2, "c":3} | "a":1, "b":2, "c":3 | use dict.items(), keys(), values() method for loops |
