Before swallowing any Python solution, you should
realize, the values (value, error) you are using are
a non sense :
1.03789291 +/- 0.00089
You express "more precision" in the value than
in the error.
As ex, in a 1.234(5) notation, the "()" is usually
used to indicate the accuracy of the digit in "()".
Typographically, the "()" is sometimes replaced by
a bold digit ou a subscripted digit.
