ok!



    LisX= [x for x in range(10) ]

    print( sum( LisX ))
    print( max( LisX ))

    print( sum( x for x in range(10) ) )
    print( max( x for x in range(10) ) )

    print( * LisX )

    print( max( * LisX ))
    print( sum( LisX ))        # same as before
    # print( sum( * LisX )) <------- Bad syntax !!!

                       TypeError: sum() takes at most 2 arguments (10 given)

                (A)   print( max( * LisX ))

What's most surprising is....     (A)  is ok, and  (B) is not.

           even tho'   max() and sum()  have   (basically)  the same syntax...  ( takes one arg ,  whch is a list )



i've been programming for many years...        ( just knew to Python )
