How can I sum user input numbers whilst in a loop?

Question

I'm trying to get the sum of numbers that a user inputs in a loop, but I can't get it to include the first number input - here's what I have so far

number = int(input("Enter a number"))
total = 0
while number != -1:
 number = int(input("Enter another number"))
 total += number
else:
  print(total)

Probably something easy I'm missing but I'm stumped ( i am a beginner as you can tell)

I have tried changing the name of the first variable number but I end up in a constant loop even when number = -1

Answer 1

number = int(input("Enter a number"))
total = 0
while number != -1:
    total += number
    number = int(input("Enter another number"))
else:
    print(total)

Just move the summation one line above.
