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:

import math print math.log(1.5) 

Can someone tell how to solve this issue?

Answer 1

From the documentation:

With one argument, return the natural logarithm of x (to base e).

With two arguments, return the logarithm of x to the given base, calculated as log(x)/log(base).

But the log₁₀ is made available as math.log10(), which does not resort to log division if possible.
