How to concatenate two integers in Python?

Question

How do I concatenate two integer numbers (for example: 10 and 20) in Python to get a returned value of 1020?

Answer 1

Just to give another solution:

def concat_ints(a, b):
    return a*(10**len(str(b)))+b

>>> concat_ints(10, 20)
1020

Answer 2

The best way to do this in python was given in the accepted answer - but if you want to do this in jinja2 templates - the concatenation operator ~ gives you a neat way of doing this since it looks for the unicode representation of all objects, thus, you can 'concatenate integers' as well.

That is you can do this (given a=10 and b=20):

{{ a ~ b }}
