Convert DD (decimal degrees) to DMS (degrees minutes seconds) in Python?

Question

How do you convert Decimal Degrees to Degrees Minutes Seconds In Python? Is there a Formula already written?

Answer 1

Here is my updated version based upon Paul McGuire's. This one should handle negatives correctly.

def decdeg2dms(dd):
   is_positive = dd >= 0
   dd = abs(dd)
   minutes,seconds = divmod(dd*3600,60)
   degrees,minutes = divmod(minutes,60)
   degrees = degrees if is_positive else -degrees
   return (degrees,minutes,seconds)

Answer 2

Just a couple of * 60 multiplications and a couple of int truncations, i.e.:

>>> decdegrees = 31.125
>>> degrees = int(decdegrees)
>>> temp = 60 * (decdegrees - degrees)
>>> minutes = int(temp)
>>> seconds = 60 * (temp - minutes)
>>> print degrees, minutes, seconds
31 7 30.0
>>> 

Answer 3

This is my Python code:

def DecimaltoDMS(Decimal):
    d = int(Decimal)
    m = int((Decimal - d) * 60)
    s = (Decimal - d - m/60) * 3600.00
    z= round(s, 2)
    if d >= 0:
        print ("N ", abs(d), "º ", abs(m), "' ", abs(z), '" ')
    else:
        print ("S ", abs(d), "º ", abs(m), "' ", abs(z), '" ')
