pythonRunScript -- execute a sequence of Python statements

Description

Execute a sequence of statements as if they were read from a Python file. This is for multi-line code that might contain definitions, control structures, imports, etc. It is great for running Python code from a file.

The return value is a Python dictionary containing all the variables defined in the global scope.

i1 : pyfile = temporaryFileName() | ".py"

o1 = /tmp/M2-60425-0/0.py
 
i2 : pyfile << "import math" << endl

o2 = /tmp/M2-60425-0/0.py

o2 : File
 
i3 : pyfile << "x = math.sin(3.4)" << endl << close

o3 = /tmp/M2-60425-0/0.py

o3 : File
 
i4 : get pyfile

o4 = import math
     x = math.sin(3.4)
 
i5 : pythonRunScript oo

o5 = {'math': <module 'math' (built-in)>, 'x': -0.2555411020268312}

o5 : PythonObject of class dict

The Global option may be used to pass a globals dictionary so that variables may be shared between scripts.

i6 : pythonRunScript("y = math.cos(x)", Global => oo)

o6 = {'math': <module 'math' (built-in)>, 'x': -0.2555411020268312, 'y':
     0.9675266635316214}
