Python Correctly Trim Decimals

sample.py

import decimal

def trim_decimal(value):
    if isinstance(value, (decimal.Decimal, float)):
        # I think format was something Django specific, because I don't know where it came from or what it does.
        value = format(value, 'f')                                                
                                                                                  
    s = str(value)                                                                
    return s.rstrip('0').rstrip('.') if '.' in s else s   

Missing an extra ')' on line 4

format is a Python built-in @eligundry. And you just gave me my first example of using it. It calls the __format__ magic method, which has it's own little special formatting DSL built-in and what not. Just supports advanced string casting for an object into different representations, I do believe (e.g., i for int, and f for float).
