获取变量类型(type)

x = 5
s = "geeksforgeeks"
y = [1,2,3]
print(type(x))  # class 'int'
print(type(s))  # class 'str'
print(type(y))  # class 'list'

用于存储数据集的四种数据类型

List、Set、Dictionary、Tuple:

Type Example Features
Tuple (1, 2, 3, 4) ordered, unchangeable, allow duplicates
List [1, 2, 3, 4] ordered, changeable, allow duplicates
Set {1, 2, 3, 4} unordered, unchangeable, do not allow duplicates
Dictionary {“a”: 1, “b”: 2, “c”: “3”, “d”: “4”} unordered, changeable, does not allow duplicates
