what's this python syntax dict(name=name)?

I've encounter this syntax in the srapy documentation.

>>> abc = ['a', 'b', 'c']
>>> dict(abc=abc)
{'abc': ['a', 'b', 'c']}

There doesn't seem to have this syntax mentioned in the python dict documentation. What is this syntax called?

There is nothing special, dict() can take keyword arguments as well as positional arguments. You can read the docs on dict().

So in your code snippet dict() just take single keyword argument.

This use keyword arguments.

It is roughly the same as:

def make_dict(**kwargs):
    return kwargs

In your case,

abc = ['a', 'b', 'c']
dict(abc=abc)

means:

dict(abc=['a', 'b', 'c'])

which is the same as:

{'abc': ['a', 'b', 'c']}
