I am new to python. I have a few questions coming from an armature!

It will if people do not make the same mental mistake when writing a 
def, because they think def functions and 'lambdas' behave differently.

I can't remember every seeing "my def function in a loop does not work 
right" while "my lambda in a loop does not work right" is distressingly 
common.  What I don't know is whether the sparsity of the former type of 
report is because those subject to the error get it right when they use 
def in a loop or because they never use def in a loop.
