All geek questions in one place

Am I using an integer or float?

This is the model in the Google App Engine:

class Rep(db.Model):
    mAUTHOR = db.UserProperty(auto_current_user=True)
    mUNIQUE = db.StringProperty()
    mCOUNT = db.IntegerProperty()
    mDATE = db.DateTimeProperty(auto_now=True)
    mDATE0 = db.DateTimeProperty(auto_now_add=True)
    mWEIGHT = db.FloatProperty()

So, mCOUNTis an integer, and mWEIGHTis a float. I calculate the age of an element as follows:

    age1 = datetime.datetime.now() - rep.mDATE0
    age_hour = float(age1.seconds) / 3600
    rep.mWEIGHT = float((rep.mCOUNT - 1) / (age_hour + 2)**1.5)

But when I try a query like this:

QUERY = Rep.all()
QUERY.filter("mAUTHOR =", user)
QUERY.order("-mWEIGHT")
RESULTS = QUERY.fetch(10)    

for result in RESULTS:
    self.response.out.write("mUNIQUE: <b>%s</b> | "
                                "mWEIGHT: %f | "  
                                "mCOUNT: %s | <br />"  
                             % (result.mUNIQUE, 
                                result.mWEIGHT,
                                # line 103                               
                                result.mCOUNT,
                                ))

I get TypeErrorin line 103, which

result.mCOUNT,
TypeError: a float is required

Why will mCOUNT float? By the way, an error occurs only if the item is not in the data store, and it is recorded for the first time using the sentence else if loop.

Can you help me use the correct type? Thank you for your help.

EDIT

I just noticed that for mWEIGHTformatting the strings for mWEIGHTI used %f, and changing this problem to %sseems to solve the problem (but I don’t know why. Is it because mWEIGHT=None?):

for result in RESULTS:
    self.response.out.write("mUNIQUE: <b>%s</b> | "
                          # changing %f to %s appears to solve the problem.
                            "mWEIGHT: %f | "  
                            "mCOUNT: %s | <br />"  
                         % (result.mUNIQUE, 
                            result.mWEIGHT if result.mWEIGHT is not None else 0.0,
                            result.mWEIGHT,                                           
                            result.mCOUNT,
                                    ))

And here are some meanings:

mUNIQUE: A | mWEIGHT: 0.299954933969 | mCOUNT: 2 | 
mUNIQUE: Z | mWEIGHT: 0.0 | mCOUNT: 1 | # With answer by TokenMacGuy 
mUNIQUE: R | mWEIGHT: None | mCOUNT: 1 | # with %f changed to %s 
mUNIQUE: P | mWEIGHT: None | mCOUNT: 1 | # with %f changed to %s

, rep.mWEIGHT else?
