内置数据类型

名称 说明
文本类型 str
数值类型 int, float, complex
序列类型 list, tuple, range
映射类型 dict
集合类型 set, frozenset
布尔类型 bool
二进制类型 bytes, bytearray, memoryview

获取数据类型

  • 您可以使用 type() 函数获取任何对象的数据类型
  1. x = 10
  2. print(type(x))

设置数据类型

例 数据类型
x = “Hello World” str
x = 29 int
x = 29.5 float
x = 1j complex
x = [“apple”, “banana”, “cherry”] list
x = (“apple”, “banana”, “cherry”) tuple
x = range(6) range
x = {“name” : “Bill”, “age” : 63} dict
x = {“apple”, “banana”, “cherry”} set
x = frozenset({“apple”, “banana”, “cherry”}) frozenset
x = True bool
x = b”Hello” bytes
x = bytearray(5) bytearray
x = memoryview(bytes(5)) memoryview

设定特定的数据类型

示例 数据类型 说明
x = str(“Hello World”) str
x = int(29) int
x = float(29.5) float
x = complex(1j) complex
x = list((“apple”, “banana”, “cherry”)) list
x = tuple((“apple”, “banana”, “cherry”)) tuple
x = range(6) range
x = dict(name=”Bill”, age=36) dict
x = set((“apple”, “banana”, “cherry”)) set
x = frozenset((“apple”, “banana”, “cherry”)) frozenset
x = bool(5) bool
x = bytes(5) bytes
x = bytearray(5) bytearray
x = memoryview(bytes(5)) memoryview
