Print multiple newlines

printnl.py

def printnl(lines=1):

    '''Print a variable number of empty lines to the screen

    Keyword arguments:

    lines --    Number of empty lines to print.
                Defaults to 1.

    Returns: string
    '''

    try:
        '''Try to convert input to a float first, because a naked float can be
        converted to an integer, but not a float in a string'''
        lines = float(lines)

        '''now convert it to an integer, because range won't work with a float'''
        lines = int(lines)
    except:
        '''Obviously, we either don't have a number, or we have some insane float
        like infinity, so we should raise an exception'''
        raise ValueError("printnl: Value must be an integer.")


    if lines < 0:
        ''' If lines is a negative value raise a value error '''
        raise ValueError('printnl: Integer must be a positive value.')

    for c in range(lines):
        ''' print however many lines that lines equals '''
        print('')

Simple method I created for when I need more than one newline on console output.
