Not Printing stmt in for loop
Here I ahd a piece of code to execute my custom python function
just i executed via python shell ,so i used print statement to know some
values but it does't respond anything
May i know the reason please?
this is the code which i executed successfully
">>> for i in cr:
... tic, mktprice,exp_date, e, ep, c, cp = i
... expd = datetime.strptime(exp_date, "%Y-%m-%d %H:%M:%S")
... cd = datetime.combine(datetime.now().date(),
datetime.time(datetime(12,12,12,0,0,0,0))) - timedelta(days=8)
... datediff = expd - cd
... current_date = cd.strftime("%Y-%m-%d")
... days_to_expiry = datediff.days
... mktprice, e, ep, c, cp = float(mktprice), float(e), float(ep), float(c),
float(cp), float(s), float(sp)
... print days_to_expiry
... print mktprice
...
>>>
cr is the data that red from csv file.So i is the row from a csv file
why it doesn't print anything?
it is just a simple python part

tags = map(lambda x:Tag.objects.get(name=x),
site_tags) ##my dynamic operation for 'tags' fields
self.fields["tags"].queryset = tags
class Meta:
model = Job
fields=('code', \
'name', \
'description', \
'company', \
'url',\
'tags', \
'state',\
'city', \
'postedby'\
)
description = forms.CharField(widget=widgets.\
