How to use multiple types?

[AmikoAce]

Hi,

I tried the following code, attempting to use two types :
@params(bool,float,float)
@rtype(float)
def IfCond(c,a,b):
if c==True :
return a
return b

recevied the following error:

File "twoTypes.py", line 64, in IfCond
if c==True :

TypeError: 'bool' object is not callable

I wanted my function to receive a boolean value (produced by a function with a boolean rtype, for example) and return either a or b, depending upon that value

Could anyone please correct my code, or provide a working example with a boolean-returning function, used by a float-returning function?

Thanks in advance!
Ami
