Python conversion assist

I'd be very grateful for some python code assist for the issues below:

1) - I used the code below for AS date calculations. Is this necessary for date calculations with Python?
set dt to do shell script "/bin/date \"+%A, %b %d at %H:%M\""
set theHour to (do shell script "date +%H") --as integer
set theMinute to (do shell script "date +%M") --as integer

2) Boolean logic:
if VarA or VarB then
and
if VarA and VarB then

3) Below are lines to calculate time for populating a ad hoc time/date action (e.g., >60 min adds an hour, >24 hrs adds a day),. Maybe this isn't necessary for Python?
--calculate time to dim lights:
set dimMin to theMinute + onTym
set dimHour to theHour
if dimMin ≥ 60 then
set dimMin to dimMin - 60
set dimHour to dimHour + 1
if dimHour > 23 then
set dimHour to dimHour - 24
end if
end if

set dimTime to dimHour & ":" & dimMin & ":" & offSec as string
log dimTime using type "fYrdLts dimTime"

--calculate time to turn lights off:
set offMin to theMinute + onTym + dimTym
set offHour to theHour
if offMin ≥ 60 then
set offMin to offMin - 60
set offHour to offHour + 1
if offHour > 23 then
set offHour to offHour - 24
end if
end if
set offTime to offHour & ":" & offMin & ":" & offSec as string
log "offTime" & offTime using type "fYrdLts offTime"

--enable and populate schedule items


***But I would like to know how to create an ad hoc time/date action, replacing the AS code below:
set the time trigger type of time date action "fYrdLtsDIM" to absolute
set the date trigger type of time date action "fYrdLtsDIM" to everyDay
set the absolute trigger time of time date action "fYrdLtsDIM" to date dimTime

4) More Boolean logic:
if ("16:00:00" > offTime or offTime ≥ "22:00:00") then


Thank you in advance for any assistance.

Probably not. You certainly don't need to run a shell script. I recommend you read this page, and concentrate on the time.strftime() function.

https://docs.python.org/2/library/time.html

Code: Select all

import time
now = time.time()
theHour = now.strftime("%H")
theMinute = now.strftime("%M")


2) Boolean logic:
if VarA or VarB then
and
if VarA and VarB then

Code: Select all

if varA or varB:
    # do something

if varA and varB:
    # do something


Take a look at the time functions I posted above, then post your #3 again after you've tried to convert it.

You might also look at https://docs.python.org/2/library/datetime.html

AS requires you to work with strings, break down the time components, manipulate them, them reconstruct the string. That's not how you do it in Python. In Python you get the time as either a float (using the time functions) or a datetime object (using datetime), manipulate that, and only construct a string at the end if you need it.

I am trying (with no success) to use the Indigo Open Scripting Shell Plugin to check the value of an Indigo variable and turn on a lamp. I am confused by how to get the variable into the Python world, how to convert it into a useful state (unicode???). I'm getting a variety of errors: unexpected indent, invalid syntax, name not defined, etc. I have tried to copy from the scripting tutorial, but it isn't helpful at my level.
Questions:
1) is it necessary to bring an indigo variable into Python (in AS, I did this with the 'set' command, e.g., set varA to the (value of variable "ambientLight") as integer)?
2) do I need to tell Python the nature of a particular variable, e.g. string, integer?
3) do I create the Python script in Text Editor and paste it as embedded code in Indigo, or, alternatively,
4) is there a Python script editor that I should be using? Searching, there are several. Is one recommended for Indigo purposes?
Basic stuff, but with a little help, perhaps I can move forward.

Could someone please show me the code to do the following: test an Indigo variable, "ambientLight" for an integer value;
1) if it needs to be imported into Python, set Python "VarA" to value of Indigo Variable "ambientLight"; and
2) if Python variable "VarA" (or indigo variable "ambientLight") is > 100, turn on a load, "lampA".

Please include any Python opening and closing lines, e.g., Tell... and endTell.
Thank you

Questions:

Yes

2) do I need to tell Python the nature of a particular variable, e.g. string, integer?

Generally not, as long as you retrieve it as the correct type. By default, Indigo variables are strings, so you need to specify that you want it as an integer.

3) do I create the Python script in Text Editor and paste it as embedded code in Indigo, or, alternatively,

Use a text editor, not but don't use TextEdit. It tries to do formatted text, which messed up the Python interpreter.

4) is there a Python script editor that I should be using? Searching, there are several. Is one recommended for Indigo purposes?

I recommend BBEdit. You can use the free version.

Could someone please show me the code to do the following: test an Indigo variable, "ambientLight" for an integer value;
1) if it needs to be imported into Python, set Python "VarA" to value of Indigo Variable "ambientLight"; and
2) if Python variable "VarA" (or indigo variable "ambientLight") is > 100, turn on a load, "lampA".

You do realize that for your example, scripting is not needed? That's all easy to do with Indigo UI directly.

Code: Select all

import indigo   # only needed for external scripts

varA = indigo.variables[717359973].getValue(int)     # use DeviceID of "ambientLight"
if varA > 100:
    indigo.device.turnOn(1234567890)                # use DeviceID of 'lampA'


Please include any Python opening and closing lines, e.g., Tell... and endTell.

Python doesn't use that stuff.

Thank you - that's very helpful, and timely.
I realize scripting isn't necessary for my example, but it is part of a more complex script. Believe me - if I don't need to use Python, I'm happy not to.
Regarding question #3, the text editor I should use for saved Python scripts is also BBEdit?
By the way, I'm tossing my Indigo keypads (and some switches) after most of the keypads failed, in favor of Lutron Radio Ra2. I believe you are responsible for the Lutron plugin - in which case, thanks for that too.

I like BBEdit for most all of my programming work. If you create a file with a .py extension, it knows it's Python and does some nice color coding and name completion.

Close, but...

Python 2.7.10 (default, Oct 23 2015, 19:19:21)
[GCC 4.2.1 Compatible Apple LLVM 7.0.0 (clang-700.0.59.5)]
Connected to Indigo Server v7.3.1, api v2.1 (localhost:1176)
>>> varA = indigo.variables[1132180415].getValue(int) # use DeviceID of "ambientLight"
>>> if varA > 100:
... indigo.device.turnOn(1580115691) # use DeviceID of 'lampA'
...
...

I ran this in the scripting plugin. I can turn on the device with the second line, but the conditional is not working. The value of the variable is 1352.0, so guessing that the issue is that it isn't an integer? - if so, the alternative to 'int'?

It's best if you post code snippets like these by using the Code button in the editor window. Like this:

>>> if varA > 100:

...
...


It helps us to spot issues with spacing and whatnot.

Code: Select all

varA = indigo.variables[717359973].getValue(int)     # use DeviceID of "ambientLight"
if varA > 100:
    indigo.device.turnOn(1234567890)                # use DeviceID of 'lampA'

See how the last line is indented (by 4 spaces)? That indentation is important.

I found 'myFloat' associated with unicode, but 'int' is much simpler. Is there an equivalent?
Where can I find this stuff without bugging the forum?

Code button: that sounds like a very helpful hint. - except, where is the code button? I just installed BBEdit, and there is a "C" on the top, but some choices that don't look like what you are suggesting.
I copy/pasted the result that wasn't very helpful from the OpenScriptingShell plugin - and I'm guessing there is no coding button available there.

Do an on-line Python tutorial. Like https://www.learnpython.org or maybe Code Academy. And then read the scripting guide in the Wiki, which explains how to deal with Indigo specific things.

If you want the variable value as a float, use .getValue(float) instead. But that's not your issue.

Dave was referring to the forum's post editor has a "Code" button. If you don't use that, we can't tell if you have your indentation correct. And Python is ALL about the indentation.

Runs!
Thanks.
Can you provide the URL for the forum's post editor?
Now - let's see how I can put this snippet to use.
Thanks again.

Beside 'int' and 'float', what do I use for 'boolean' and 'strings'?
The code you have suggested is much more concise than the examples on the indigo forum.
As for scripting tutorials, I tried two of them and found that I couldn't seem to get past the second lesson. Too many other things to do.
I learned apple scripting this way - by example - and hope that Python will come along quickly.

What do you mean URL? It's this button:
