# 导入 sys 模块,虽然在这个例子中不直接需要,但在复杂应用中可能会有用importsys 1. 2. 步骤2:定义获取类型的函数 创建一个名为get_type的函数,接受一个参数并返回该参数的类型。 defget_type(variable):""" 获取变量的类型 参数: variable -- 需要检查类型的变量 返回: str -- 变量类型的字符串表示 "...

oooooooooooooo Python Type Checking oooooooooooooo 是时候给我们第一个类型加个提示了!要向函数中添加关于类型的信息,只需如下注释其参数和返回值: def headline(text: str, align: bool = True) -> str: ... text: str 意思是text值类型是str, 类似的, 可选参数 align 指定其类型为bool并给定默认值Tru...
Python 3.6。基于《PEP 526 Syntax for Variable Annotations》(延伸阅读链接 9) 添加了用来注释变量 (包括类变量和实例变量) 类型的语法 Python 3.7。基于《PEP 563 Postponed Evaluation of Annotations》(延伸阅读链接 10)支持了延迟标注求值,我之前专门写过from __future__ import annotations介绍它 ...
determine a variable's type in Python you can use the type() function. The value of some objects can be changed. Objects whose value can be changed are called mutable and objects whose value is unchangeable (once they are created) are called immutable. Here are the details of Python data...
