Unpacking Argument Lists

更多
#The reverse situation occurs when the arguments are already in a list or tuple 
#but need to be unpacked for a function call requiring separate positional 
#arguments. For instance, the built-in range() function expects separate start 
#and stop arguments. If they are not available separately, write the function 
#call with the *-operator to unpack the arguments out of a list or tuple:

print range(3, 6)             # normal call with separate arguments

args = [3, 6]

print range(*args)            # call with arguments unpacked from a list
