本节中我们介绍三种数据类型转换方式,分别为整型(int),浮点型(float),字符串型(str)。 整型(int) 假设我们有浮点型变量x,其取值为2.0,以及字符串型变量y,其取值为“3”,我们将这两个变量均变为整型变量: x=2.0y="3"x=int(x)y=int(y)print(x)print(y)>>>2>>>3 浮点型(float) 假设我们有整型变...

String (str): Strings are used for text. For example, “Hello, Python!” is a string. To define strings, you can use single or double quotations. Boolean (bool): Booleans have two values: `True` and `False`. They are used to represent true or false conditions, like whether it’s ...
but there is something in the works to allow this:https://github.com/python/mypy/issues/9773 for now i am doing the equivalent of this when passing in a type union: casted:str|int= safe_cast(cast(type,str|int), string) since i know using a type union will work with my code ...
