Float object is not callable python

Question

I have a simple script trying to calculate the area and circumference of a circle. On the first iteration of the loop, it works just fine. However, on the second it breaks saying "'float' object is not callable". Any ideas on what is wrong?

Error Message:

Traceback (most recent call last):
  File "C:/Users/Administrator/Google Drive/School/Spring 2015/Scripting/ITD2313-Portfolio-GandyBrandon/Assignments/Hands-on & Labs/Question1.py", line 16, in <module>
    area = area(radius)
TypeError: 'float' object is not callable

Code:

import math
finished = False
def area(number):
    area = math.pi * (number**2)
    return area
def circum(number):
    c = 2 * math.pi * number
    return c
while (finished == False):
    radius = 0
    radius = int(input("Please input the radius: "))
    if radius <= 0:
        print ("Exitting the program...")
        finished = True
    else:   
        area = area(radius)
        circum = circum(radius)
        print (area)    
        print (circum)

You have variables named area and circum, and functions with the same name. Don't do that. Also, next time, please post the full text of the error or traceback, as it points directly to where the error is occurring. — MattDMo

Not answering your question, but your variable finished is a boolean. You should not explicitly write while finished == False, you can just use the boolean itself, like this: while finished or while ! finished. — JNevens

You are overriding the function definition:

You're setting

area = area(radius)
circum = circum(radius)

and in the second loop you're going to do the same and so on. Change the name of the function to something like calculate_area or calculateArea and similarly for circum (i.e. calculate_circum or calculateCircum) to avoid such confusions.

No problem. You should generally try to stick to rules when naming objects in general, you'll see that you'll face such problem less frequently and it will save you time.
