Description
The EXECPYTHON() function runs Python code. The lines of code are contained in <expC>, which can be a text constant, a filename, a character variable, or a character or memo field. The EXECPYTHON() function can handle blocks of code. Individual lines of code must be separated by a CHR(13) carriage return character. If a filename.py is specified it is loaded and executed. Inside the .py file, to return a value assign a result to returnvalue
Note that if a filename.py is specified and a list of arguments are specified as <expr>... sys.argv in python is an array of arguments. This provides a consistent way to incorporate python functions in your LianjaScript code.
e.g.
- filename.py
import neededmodules
- extract arguments specified on execPython()
arg1 = sys.argv[0] arg2 = sys.argv[1]
- execute your code
- now return a value
returnvalue = "Ok"
Example
// Character field create table if not exists scripts (script char(200)) if not used("scripts") use scripts endif select scripts append blank replace script with 'for i in range(9):' + CHR(13)+ '# process commands' + CHR(13) execpython(script) // Text constant execpython('for i in range(9):' + CHR(13) + '# process commands' + CHR(13)) // Memory variable m_script = 'for i in range(9):' + CHR(13) + '# process commands' + CHR(13) execpython(m_script)
