前言 如果把时间拉到一年前我肯定不会写关于类型提示 (Type Hint) 或者 mypy 的内容。印象里在之前的博客或者知乎回答中明确提过「拒绝在代码中指定变量类型」,另外一个原因是 mypy 和类型提示相关的功能还在不断完善,业界还没有大范围应用。 众所周知,Python 是动态类型
基础数据类型像是int,float,str,bytes 可以在type hints中直接使用,其他已经封装好的类,也可以直接在type hint中使用。当然抽象类(Abstract Base Classes)在type hint中也很有用。 Optional and Union types 上面2个类型还是比较常见的,我们先来看个例子: ...
If you’re familiar with Python’s built-in types, then you won’t need to add type hints to these variables because you’ll soon know that you have a string, integer, and floating-point value, respectively. So, in this situation, you’re okay to skip the type hint. Also, your ...
NameTypeRequiredDescription output_schema string ✔️ A type literal that defines the output schema of the tabular data, returned by the Python code. The format is: typeof(ColumnName: ColumnType[, ...]). For example, typeof(col1:string, col2:long). To extend the input schema, use ...
Note: To reference a protocol within its definition, you must include its name as a string literal to avoid errors. That’s because you can’t refer to a type that isn’t fully defined yet. While this limitation will change in the future, for now, you can use a future import as an...
