Click command what is

Values are passed to the commands via options or arguments. Options are added with the click. Values in options follow the name of the option while arguments are taken positionally. We install the click module. For coloured output, we also need the colorama module. Click uses the echo instead of the print. It increases compatibility and adds colouring support.

We can specify the argument types, including int, float, str, bool, choice and various ranges. The default one is str. This is good, because click uses the extra decorators e.

Notice that the click. Better not! From here you can do all sorts of stuff which is all outlined in the excellent click documentation. It will give you information about all of the arguments, their types, and more.

Instead, we want to interact with the code via the package. Further, if you cd into the place where the code is and run python cli. The solution to the problem is to use the -m flag in the python CLI. You can now run the CLI using python -m superanalysis.

As an aside, this also works in subpackages. As one big text block, which I will set as the default, by sentence, or by paragraph. For just an example of what it looks like to have two python click command groups running, skip down to the last code segment. As you can see from the two images below, our new command line tool can recognize input and run the commands correctly from that.
