Ekeel.Interop.Python

A wrapper around PythonNet that allows for execution of Python code.

using Ekeel.Interop.Python; var pythonHandler = new Handler(); var variables = new Dictionary<string, object>(); variables.Add("test_var", "test_var_val"); pythonHandler.RunFromFile(@"C:\tmp\test.py", "test_var", variables);

Handler

Class Handler handles execution of Python scripts using a local Python setup.

Constructors

Handler()

This constructor initializes a new Handler using a .env file.

Notes:

• Read required variables from a local .env file.

Examples:

var pythonHandler = new Ekeel.Interop.Python.Handler();

Handler(string pythonDllPath)

This constructor initializes a new Handler.

Parameters:

• pythonDllPath
  • The local path of the Python DLL to use for the runtime.

Examples:

var pythonHandler = new Ekeel.Interop.Python.Handler(@"C:\tmp\test.dll");

Handler(string pythonDllPath, string pythonHome)

This constructor initializes a new Handler.

Parameters:

• pythonDllPath
  • The local path of the Python DLL to use for the runtime.
• pythonHome
  • The path to the python home directory.

Examples:

var pythonHandler = new Ekeel.Interop.Python.Handler(@"C:\tmp\test.dll", @"C:\python\");

Instance Methods

void RunFromString(string code)

This method runs a string of Python code.

Parameters:

• code
  • The Python string to execute.

Examples:

var pythonHandler = new Ekeel.Interop.Python.Handler(); pythonHandler.RunFromString("import sys; sysversion = sys.version");

void RunFromString(string code, Dictionary<string, object> variables)

This method runs a string of Python code.

Parameters:

• code
  • The Python string to execute.
• variables
  • Dictionary containing the key/values of variables to set.

Examples:

var pythonHandler = new Ekeel.Interop.Python.Handler(); var variables = new Dictionary<string, object>(); variables.Add("test_var", "test_var_val"); pythonHandler.RunFromString("import sys; sysversion = sys.version; print('test_var')", variables);

TResult RunFromString<TResult>(string code, string returnVariable)

This method runs a string of Python code.

Parameters:

• code
  • The Python string to execute.
• returnVariable
  • The variable to read from the scope.

Returns:

• The value of the returnVariable from the scope.

Exceptions:

• KeyNotFoundException
  • The returnVariable was not found.

Examples:

var pythonHandler = new Ekeel.Interop.Python.Handler(); var retVal = pythonHandler.RunFromString("import sys; sysversion = sys.version", "sysversion");

TResult RunFromString<TResult>(string code, string returnVariable, Dictionary<string, object> variables)

This method runs a string of Python code.

Parameters:

• code
  • The Python string to execute.
• returnVariable
  • The variable to read from the scope.
• variables
  • Dictionary containing the key/values of variables to set.

Returns:

• The value of the returnVariable from the scope.

Exceptions:

• KeyNotFoundException
  • The returnVariable was not found.

Examples:

var pythonHandler = new Ekeel.Interop.Python.Handler(); var variables = new Dictionary<string, object>(); variables.Add("test_var", "test_var_val"); var retVal = pythonHandler.RunFromString("import sys; sysversion = sys.version", "sysversion", variables);

void RunFromFile(string scriptFile)

This method runs a Python script.

Parameters:

• scriptFile
  • he path to the Python script to execute.

Examples:

var pythonHandler = new Ekeel.Interop.Python.Handler(); pythonHandler.RunFromFile(@"C:\tmp\test.py");

void RunFromFile(string scriptFile, Dictionary<string, object> variables)

This method runs a Python script.

Parameters:

• scriptFile
  • he path to the Python script to execute.
• variables
  • Dictionary containing the key/values of variables to set.

Examples:

var pythonHandler = new Ekeel.Interop.Python.Handler(); var variables = new Dictionary<string, object>(); variables.Add("test_var", "test_var_val"); pythonHandler.RunFromFile(@"C:\tmp\test.py", variables);

TResult RunFromFile<TResult>(string scriptFile, string returnVariable)

This method runs a Python script.

Parameters:

• scriptFile
  • he path to the Python script to execute.
• returnVariable
  • The variable to read from the scope.

Returns:

• The value of the returnVariable from the scope.

Exceptions:

• KeyNotFoundException
  • The returnVariable was not found.

Examples:

var pythonHandler = new Ekeel.Interop.Python.Handler(); pythonHandler.RunFromFile(@"C:\tmp\test.py", "sysversion");

TResult RunFromFile<TResult>(string scriptFile, string returnVariable, Dictionary<string, object> variables)

This method runs a Python script.

Parameters:

• scriptFile
  • he path to the Python script to execute.
• returnVariable
  • The variable to read from the scope.
• variables
  • Dictionary containing the key/values of variables to set.

Returns:

• The value of the returnVariable from the scope.

Exceptions:

• KeyNotFoundException
  • The returnVariable was not found.

Examples:

var pythonHandler = new Ekeel.Interop.Python.Handler(); var variables = new Dictionary<string, object>(); variables.Add("test_var", "test_var_val"); pythonHandler.RunFromFile(@"C:\tmp\test.py", "sysversion", variables);
