How to change decimel to fraction

Question

Is there any easy function or method by which a decimel can easily be turned into fraction or vice versa in python?
Like a = 2.3333333
a.method() or func(a) and the return will be 2 1/3 and vice versa.

Answer 1

You can use the Fraction module
Ex:
>>>from fractions import Fraction
>>>Fraction(0.2)
However, it would end up with strange very long numbers for both numerator and denominator:
Fraction(3602879701896397, 18014398509481984)
To avoid this, add .limit_denominator() to your expression.
Ex:
>>>Fraction(0.2).limit_denominator()
Fraction(1, 5)
Add str method to make the result more readable.
Ex:
>>>str(Fraction(0.2).limit_denominator())
'1/5'
>>>str(Fraction(0.2))
'3602879701896397/18014398509481984'

Answer 2

Here is a quick example, it only does decimal to fraction, and its a little ugly.
