Hello,

I would like to create a

Olivier

I would like to create a

`lambda`

function accessing Numpy functions, and only them. I can do the following:import numpy eval('exp(1)', {'__builtins__': None}, numpy.__dict__)

`Output:2.7182818284590451`

However, I get an error when I create a `lambda`

function in that way:f = eval('lambda x:exp(1)', {'__builtins__': None}, numpy.__dict__) f(0)

`Error:TypeError: 'NoneType' object is not subscriptable`

Could you explain why and provide a working example?Olivier
