# python program to find the sum of series: 1 + x² + x³ + ... + xⁿ
n = int(input('Enter the value of n: '))
x = int(input('Enter the value of x: '))
sum_of_series = 0
for i in range(n+1):
sum_of_series += pow(x,i)
print('Sum of the series is:', sum_of_series)
- Input the value of x and n from user as integer type
- define a variable with value of zero to add up till the sum of series, this must be outside the loop, else each time the loop repeats value will set to zero defeating the purpose.
- we use for loop with range of i varying from 0 to n (remember this is not for infinite series) giving the power of x from 0 to n
- evey iteration we add x^i to the sum
- finally print the sum of series

sum = 0
temp = num
while temp > 0:
digit = temp % 10
sum += digit ** 3

if num == sum:
print(num,"is an Armstrong number")
else:

Some experts argue, however, that VoIP specifically refers to sending voice traffic over an IP network. In contrast, IP telephony is a broader umbrella term that refers to any telephone-type communication service carried over IP -- this could include faxing, text messaging and more.
