Calculate logarithm in python

Question

I am wondering why the result of log base 10 (1.5) in python = 0.405465108108 while the real answer = 0.176091259.

This is the code that I wrote:

Answer 1

If you use log without base it uses e.

From the comment

Return the logarithm of x to the given base.
If the base not specified, returns the natural logarithm (base e) of x.

Therefor you have to use:

import math
print( math.log(1.5, 10))
