Good morning,
I have downloaded the version 3.4 and I have a problem to calculate the mean.
The software does not recognise the function mean(). I am getting the following
error.
>>> mean([1, 2, 3, 4, 4])
Traceback (most recent call last):
File "", line 1, in
mean([1, 2, 3, 4, 4])

Sorry, you really can't give FunctionType an argument list.
Maybe you can wrap the function with a callable object, this way you can
change the argument list returned, and doest have to eval or compile code.

You can use the FunctionType class found in the types module (and its
friends) to create functions on the run.
And you can use the 'inspect' module to inspect existing functions, if you
need to base the new function on an existing one.
