Help with Tempature Conversion Program

[bowlofred]

Which line is line 9 in your program? Above it is a blank line.

The error is associated with taking a float object and trying to use it like a function. As an example:

>>> f = 5.2   # This makes f a float object
>>> print(f)  # we can print f
5.2
>>> f()       # but we can't call f
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'float' object is not callable

It looks like you expect that con could at some point be "Stop". But if you're setting it this way:

con = float(input("Enter the desired tempature translation: "))

Then that isn't possible. You're casting the input value to a float. If someone typed in "stop", the float() conversion would fail and would generate an error.
