It fails on any list entry that isn't a float or an int, giving a TypeError.

Efficient No, but resistant to error I can buy using try except to pass through TypeErrors.

def max_try(listarg):
    myMax = listarg[0]
    try:
        for item in listarg:
            if item > myMax:
                myMax = item
    except TypeError:
        print(f'Only numbers are supported, this entry "{item}" was not')
        pass

    return myMax


Thanks.

PS Since I am going through the list fully the only optimisation I can think of a generator to feed it seems sort of redundant. Unless of course it was a list of 10,000 numbers then maybe its useful. 

Maybe a generator with a condition that if list length is greater than 500 to chunk it into 250 lengths. 

But then If we go along this path then you could say if every other task in an application waited on it could be very important so then async await might be an option.
