Also, I don't have time right now to look into it all, but I think maybe you can't do: prompt: str | Dict, because that kind of type declaration for a union is relatively new (Python version compatibility). 👍 1 Contributor AndriyMulyar commented Jul 14, 2023 I would really ...
Python variables do not need explicit declaration to reserve memory space. The declaration happens automatically when you assign a value to a variable. The equal sign (=) is used to assign values to variables. The operand to the left of the = operator is the name of the variable and the ...

Why do not use python dictionary declaration syntax instead? Something like{alt:"", src:"/img/my_picture.png"} Because it is overloaded for html templating. "Chained-methods-call" like syntax uses less chars to type. mintalows to set/append value of tag attribute somewhere inside tag: ...
在这个例子中,我们创建了一个名为my_dict的defaultdict对象,并将默认值设置为列表。然后,我们使用append()方法向键'key'添加了两个值'value1'和'value2'。最后,打印字典的内容,可以看到键'key'对应的值是一个包含两个元素的列表。 需要注意的是,defaultdict类是collections模块中的一个高级字典类,它会自动为字...
