Python: format str float - how to hide the fractional part if it is zero?

Question

Python

Python3.4.
It is necessary to form a line with a price.
If the fractional part of the price is 0, then do not display it (the fractional part).

1. 
   >>> floatVal = 123.456
   >>> "Price: {:.2f}".format(floatVal)
   'Price: 123.46'
   
2. 
   >>> floatVal = 123.00
   >>> "Price: {:.2f}".format(floatVal)
   'Price: 123.00'
   

The fractional part is displayed in both cases. And in the second case, you need to get the string 'Price: 123'
What should the format string be?
Thank you in advance!

Answer 1

>> from decimal import Decimal
>>> quantize = Decimal('.01')
>>> print(Decimal(123.456).quantize(quantize).normalize())
123.46
>>> print(Decimal(123.00).quantize(quantize).normalize())
123

Answer 2

The price must be stored as an integer, otherwise it may become unreliable due to rounding.
