i have problems understanding 2 functions,look for help.

[Tony]

these 2 functions are

def print_end():
    print()

def nothing():
    "do nothing"

for the first function, what is meant by print with no argument?
for the second function,I just cannot understand the syntax and functionality here.
Thanks
