The wrapper function uses *args and **kwargs to pass on arguments to the decorated function. If you want your decorator to also take arguments, then you need to nest the wrapper function inside another function. In this case, you usually end up with three return statements. You can ...
*other_data (list): Additional data items to incorporate into processing. output_format (str, optional): Desired output format. Defaults to "json". **options (dict): Arbitrary keyword arguments to customize processing. Returns: str or dict: Processed data in the chosen output format. """ ....
You apply the function_name decorator to the method to define the function name, while the HTTP endpoint is set by applying the route decorator. This example is from the HTTP trigger template for the Python v2 programming model, where the binding parameter name is req. It's the sample code...
The second EAP of PyCharm 2021.2 brings a lot of improvements, both platform-wide and Python-specific. Take a look at what we have new in store for Python 3.10 support, easy package installation, work with JavaScript and TypeScript, and the debugger. Starting with this EAP, you can join ...

Tab completion frompersistent_history_filesources added with very little friction. Automatic tab completion ofargparseflags and optional arguments. Path completion easily enabled. When all else fails, custom tab completion based onchoices_providercan fill any gaps. ...

This decorator can take a single string parameter, which determines the name of the method argument whose value will be added as the query argument value of the same name.In case 2 arguments are provided, the second argument determines the actual query key name, which will be used in the ...
