You can use installable triggers in standalone and bound scripts. For example,a standalone script can programmatically create an installable trigger for anarbitrary Google Sheets file by callingTriggerBuilder.forSpreadsheet(key)and passing in the spreadsheet's ID.

Automation is the future, and Python scripts are an excellent way to get started in your automation journey. You will need a way of scheduling though in order for this automation process to not only be effective but also manageable!
Previously I wrote about how and why I built a simple web-scrapig script to notify us about our favourite food. I followed up with a post that detailed how to run and schedule Python scripts on iOS, and now I'd like to share how you can do the same with a Raspberry Pi.
While it's possible to play around and fire off simple Python scripts on iOS it has it's limitations.First, you can't truly automate running them. You can trigger them by time or location, but you will have to unlock your phone and hit OK on each trigger.Second, you can't take advantage of some of the more advanced modules. One example is Selenium, which can create virtual browser instances in the background, visit websites and take actions on them. This is not possible due to iOS's locked down architecture.On the Pi (Linux) you have no limits. You can use any module and schedule scripts to run fully automatically, whenever you like.
All right, your Pi is up and running, now you just need to configure it to run Python scripts.The good news is: there's not much to do if you are using Raspbian, as it has Python installed out of the boxOne thing you can do is download the latest version, probably because Raspbian does not have the latest release. Head over to python.org, and upgrade if necessary.But other than this you are good to go. You can copy your existing .py files and start using them with the built in IDE or Terminal straight away.Speaking of which: if you are copying over files you used on Windows or OS X, remember that on Linux you'll need a different shebang line. You probably know where to look this up, but here it is for reference:
Now to the interesting part. So far we set up our Pi and started to run python scripts on it. But logging in through RealVNC or SSH every time we want a script to run is not really convenient (with the exception if we want to trigger scripts via SSH coming from another device or service automatically, but this will be detailed in another post).If we have a web-scraping script that looks for some info on the web every day and returns some information (like the food notifier explained in my previous post), then what we want is total automation. The script should start all by it self, do it's job, and return the information.Luckily we can do that with a built in tool in Linux called CRON.
I hope this short tutorial gave you an idea how easy it is to set up a Pi and start using it for Python script automation.I think the possibilities are almost endless.Like the Food Notifier example, you can set up scripts that automatically check information on the web every day and track changes or take action on them.You can easily setup a python based chat bot that constantly runs, listens to inquiries and responds to them.You can also hook up your Pi to a Home automation system and start / stop gadgets in your home periodically or remotely from a device.
In a previous post, we talked about how to run R from the Windows Task Scheduler. This article will talk about two additional approaches to schedule R scripts, including using the taskscheduleR package on Windows and the cronR package for Linux. For scheduling Python code, check out this post.
A Simple Trigger is easy to set up and scripts that use them do not need user authorization to run. However, scripts run by a Simple Trigger cannot access user data or perform actions that would otherwise need authorization.
Power Manager can be used to automatically run a shell script each day. Shell scripts can be used to perform tasks that are difficult, or impossible, to achieve using the graphical Mac OS X interface.
Select the supported Operating Systems where the script is allowed to run. Just keep in mind that different OSes shipped with different versions of PowerShell. If you're targeting multiple OSes, make sure your scripts are compatible. If you only want to run this on Windows 10 PCs, you'd set it up like this.
On the Settings page, choose to define a new setting. In the Create Setting dialog, use the Script setting type, and choose the appropriate data type for any return value that your script may generate. In most cases, I like to use the boolean data type. That way I can simply return $true or $false from my PowerShell scripts to indicate to SCCM whether the script ran successfully. Also, take note of that checkbox for specifying script execution context and set it according to your needs.
Next, we need to create a compliance rule for this setting. Since we're just using the compliance mechanism to run a script on a schedule, the only thing that really matters is that the script runs without error. Again, I handle this by designing my scripts to return $true if they execute without error. So, the compliance rule should look like this.
Elasticsearch performs a number of optimizations to make using scripts as fast aspossible. One important optimization is a script cache. The compiled script isplaced in a cache so that requests that reference the script do not incur acompilation penalty.
All scripts are cached by default so that they only need to be recompiledwhen updates occur. By default, scripts do not have a time-based expiration.You can change this behavior by using the script.cache.expire setting.Use the script.cache.max_size setting to configure the size of the cache.
This integration allows you to write Python scripts that are exposed as services in Home Assistant. Each Python file created in the /python_scripts/ folder will be exposed as a service. The content is not cached so you can easily develop: edit file, save changes, call service. The scripts are run in a sandboxed environment. The following variables are available in the sandbox:
You can add names and descriptions for your Python scripts that will be shown in the frontend. To do so, simply create a services.yaml file in your /python_scripts folder. Using the above Python script as an example, the services.yaml file would look like: 041b061a72
