increase insertion speed in python

Question

I have a script in django which i am running on terminal to update the field values in database , there is about 3000 records to be updated , it updated but it takes so much time.

Here is the code:

getAge  = myplayer.objects.all()
for i in getAge:
    i.age  = i.age + 0.0192         # it is equilant to  1/52
    i.save()    
    print  "new age of id - " ,i.id, "is ", i.age 

I am using a MYSQL DB please suggest how can i speed up the insertion time

thanks

Answer 1

If you don't need to print new ages, you can do as follow using F :

from django.db.models import F
myplayer.objects.update(age=F('age')+0.0192)

Answer 2

from django.db.models import F    
myplayer.objects.all().update(age=F('age') + 0.192)
