How to convert degrees, min, secs to decimal degrees with Python

[nevy]

Does anyone know why this doesn't work? its meant to convert degrees, min, secs to decimal degrees. It should be simple right - but I'm very new to python (yesterday...)

 class DMStoDD:
    def__init__(self, degrees, min, sec):
        self.degrees = abs(degrees) % 360
        self.minute = abs(min) % 60
        self.second = abs(sec) % 60
    def DD:
        self.degrees = (self.degrees) % 360
        self.minute = self.minute/60
        self.seconds = self.seconds/3600
    def AsList(self):
        print [self.degrees, self.minute, self.seconds] 

also how do I run my class?

What would the input look like? Why are you using "modulo 360" for self.degrees? A degree is 1 degree, a minute is 1/60 of a degree, and a second is 1/3600 of a degree. If you intend "DD" to be a method, you need an argument tuple with "self" in it. def DD(self):

>>> degrees, minutes, seconds = 30, 25, 15
>>> decdeg = degrees+minutes/60.+seconds/3600.
>>> decdeg
30.420833333333334
>>> 

To run it, create an instance by calling the class like a function: obj = DMStoDD(degrees, minutes, seconds)

Figure it out on paper first and use google if you can't get some of the calcs to work out.

well I got it to work, there was a space missing between def and __init

the problem is I get this as a result <__main__.DDtoDMS object at 0x0216D4B0> when I want a number format (10.006)

[bvdet]

Add a __str__ method to the class definition, and print obj, where obj is an instance of DMStoDD, will write whatever you want to stdout.

You also have to add (self) to DD if you want it to be a function that is a member of the class. This is what I get using your original post:

class DMStoDD:
    def __init__(self, degrees, mins, sec):
        ## anything less than 360 will yield the same number
        self.degrees = abs(degrees) % 360
 
        ## "min" is a reserved name==minimum
        self.minute = abs(mins) % 60
        self.seconds = abs(sec) % 60
 
    def DD(self):    ## same as __init__ calcs
        self.degrees = (self.degrees) % 360
        self.minute = self.minute/60
        self.seconds = self.seconds/3600
 
    def AsList(self):
        print [self.degrees, self.minute, self.seconds]
 
DS = DMStoDD(29, 12, 30)
DS.AsList()       ## prints [29, 12, 30]
DS = DMStoDD(390, 12, 30)
DS.AsList()       ## prints [30, 12, 30]

thanks for everyones help. It works now, I think the main problem was I was using python 3 not 2. Its a bit strange that nothing seems to work in python 3 - sort, sorted doesn't work either. I kept getting DMStoDD is not defined. But it works in python 2 now. The only thing I can't get is to limit the values degrees(0-360), minutes(0-60)
