Sum of powers

Python, Math · Nov 2, 2020

Returns the sum of the powers of all the numbers from start to end (both inclusive).

  • Use range() in combination with a list comprehension to create a list of elements in the desired range raised to the given power.
  • Use sum() to add the values together.
  • Omit the second argument, power, to use a default power of 2.
  • Omit the third argument, start, to use a default starting value of 1.
def sum_of_powers(end, power = 2, start = 1):
  return sum([(i) ** power for i in range(start, end + 1)])
sum_of_powers(10) # 385
sum_of_powers(10, 3) # 3025
sum_of_powers(10, 3, 5) # 2925
