A safe max() function for empty lists

Question

Evaluating,

max_val = max(a)

will cause the error,

ValueError: max() arg is an empty sequence

Is there a bett

Answer 1

Can create simple lambda to do this:

get_max = lambda val_list: max([ val for val in val_list if val is not None ]) if val_list else None

You can call it this way:
get_max(your_list)
