Solve simple Wolfram problems in Python?

Hi all, I spent days reading documentation solo but I’m stuck.
Using Python 3.8.5 with Wolfram Client Library on Windows 10.

Goal: Input problem in Python (e.g. as string ‘2*pi’) then output solution as workable Python object (e.g. float or string “6.283”)

Sample Code (not incl. module imports):

input_problem = ‘2*pi’

output_solution = session.evaluate(wlexpr(problem))

print(output_solution)

Desired output: 6.283

Actual Output:
Times[2, Global`pi]

Output Type: <class ‘wolframclient.language.expression.WLFunction’>

Any help or direction is greatly appreciated, thank you!

Try Pi, not pi.
