282 PointsI am not sure why I am getting the error: 'int' object is not callable based on my code.
I thought I passed the argument of 3 into my square function I created and set that equal to my new variable called result and I then return the answer. I am not sure why I am getting this error.
def square(number):
square = number*number
result = square(3)
return result

Extra hints:
- don't use the same names for functions and variables
- calling a function from inside itself (unconditionally) creates an "infinite loop"

Courses Plus Student 2,662 PointsWhat you should do is return the square of the number that will be passed in, which is number * number, What you did is call the function square inside itself. You can't call a function inside itself
def square(number):
return number*number
OR
def square(number):
result = number*number
return result

282 PointsYes I had that part down but I need to call my function and pass in the argument of 3. I should store this as the result variable

231,248 PointsSure, but that task should be done after the function definition, not inside it.
