The python statement executes a Python script (program).


Parameters

This statement has four parameters:

source – Python script (source code). Note: It is very convenient to use “pipe” delimiters for this parameter, for example |||script|||. This eliminates needing to worry about the delimiters that occur in the script itself.

result – Name of the field or variable in which the result of the script will be placed. This result is any output sent to the standard console output. If this parameter is not supplied the result will be placed in the global variable ScriptResult.

folder – Folder to execute python script in (default to current database folder)

timeout – Maximum amount of time the script will be allowed to run (in seconds). If this option is not specified you can set the default using the scripttimeout statement. If this default has never been set the default is 60 seconds.


Description

This statement executes a Python script (program). This simple example takes a Panorama numeric variable, transfers it into Python, and then back out again.

local N,output
N=42
python |||i = $«N»$<br>
    print 'The value of i is', i ||||,output
message output

As shown in the example above, Panorama formulas can be embedded in the script using special tags. To embed a Panorama formula as text use

$«formula»$

The formulas are calculated in advance, then embedded into the source code as constants. For example, the formula $«2*3»$ will be embedded into the program as 6. The formula $«upper("hello world")»$ will be embedded as "HELLO WORLD".

In the case of text formulas any special characters will be encoded as necessary for a proper Python constant. For example the formula $«{"}»$ will be embedded as """.

To embed a Panorama formula with no quotes or translation use

^«formula»^
