Using a Wolfram notebook...

Create a local Wolfram Language session

Import the module:

Create a session using the default path:

• The default path depends on the environment and may also depend on the version of the Wolfram Engine being used.
• To create a session with a nondefault path, provide the path to the Wolfram Engine as the first argument, e.g.: WolframLanguageSession(‘C:/Program Files/Wolfram Research/Mathematica/12.0/wolfram.exe’).

Evaluate Wolfram Language expressions

Import the function:

Compute the squares of an array of integers:

End the the session

Terminate the session object:

• The session must be terminated to properly shut down the Wolfram Engine process.

Using the command line...

Create a local Wolfram Language session

Open a terminal window and invoke the Python interpreter:

$ python

Import the module:

>>> from wolframclient.evaluation import WolframLanguageSession

Create a session using the default path:

>>> session = WolframLanguageSession()

• The default path depends on the environment and may also depend on the version of the Wolfram Engine being used.
• To create a session with a nondefault path, provide the path to the Wolfram Engine as the first argument, e.g.: WolframLanguageSession(‘C:/Program Files/Wolfram Research/Mathematica/12.0/wolfram.exe’).

Evaluate Wolfram Language expressions

Import the function:

>>> from wolframclient.language import wlexpr

Compute the squares of an array of integers:

>>> session.evaluate(wlexpr('Map[#^2 &, Range[5]]')) 
[1, 4, 9, 16, 25]

End the the session

Terminate the session object:

>>> session.terminate()

Exit the Python shell:

>>> exit()

• The session must be terminated to properly shut down the Wolfram Engine process.
