Use this code and resolve your problem int object is not callable.
n = input('Give the value of n.')
n = int (n)
s = (((n+1))/2)**2
print ('Sum equals =', s)

This particular error aside, I think what you really want is:

sum( [i**3 for i in range(n+1)] )

when you get a error like that: "type integer is not callable", it's prabbly a syntax error / typo:

the syntax for calling a function in Python is to put parens after it:

fun()

so look and see if you have put parens after something that is not a function -- and indeed you have:

(note this UI sucks! I have to write this in a modal dialog, so I can't see the original question!)

I think you have code like:

n(1 + n)

look for the n(...) -- that is math notation for multiply, but it's python notation for call the function "n" -- it should be:

n * (1 + n)

You have to redefined your "sum" function to be an integer data type. So it is rightly telling you that an integer is not something you can pass a range.To fix this, restart your interpreter.Then all is okay.like this n = input('Give the value of n.') n = int (n) s = (((n+1))/2)**2 print ('Sum equals =', s)

use this and solve the type error : int object in not callable n = input('Give the value of n.') n = int (n) s = (((n+1))/2)**2 print ('Sum equals =', s)
