Orders under $99. $9.95. for i in range(num+1): if num == i**3: print('It is a perfect cube') break # Don't need to check more else: # Only executed if the loop ends "naturally", not via a break print('It is not a perfect . Python programming language is a high-level and object-oriented programming language. If yes, then it is a perfect cube. The idea is to check for each number from 1 to N if the cube of any of these numbers equals N. If so, then that number is the cube root of N and the N is a perfect cube. Dudeney Numbers A perfect cube is an integer whose cube root is also an integer. 1- Given a = 24 b = 576 2- acr = cbrt (a)) bcr = cbrt (b) acr = 3 and bcr = 8 3- Print cubes of 3 to 8 that comes under the range of a and b (including a and b both) 27, 64 . Here, we check the condition according to the parameters of definition 1, i.e if the sum of all the integral divisor (excluding the number) of the number is equal to the number then the number can be termed as a perfect number.
