Dynamically set decimal place of number in Python

Question

Let's say i have following variables:

something = 123456789  
decimal = 5

I want to set the decimal place of something based on the value of decimal so that for the above example i get:

something = 1234.56789

Now let's say decimal = 15 then i need to get:

something = 0.000000123456789

How to do this in the most pythonic way?

Answer 1

Simply by dividing with 10 to the power of decimal.

something = 123456789
decimal = 15
print(something / 10 ** decimal)
