While loop to add numbers in list python

I am learning python V3 and have the following problem on a homework assignment:

In this exercise, your function will receive a list of numbers, and an integer. It will add the values in the list to a total as long as the total is less than or equal to the value of the second parameter. The sum of numbers in the list will always be larger than the second parameter's value.

I came up with the following solution:

def while11[nums,maxi]:
    i=0
    total=0
    while total 0:
    sum += num
    num -= 1
print["The sum is", sum]

Output:

User input number sum

sum = 0

num = int[input["Enter a number: "]]
if num < 0:
    print["Please enter a positive number"]
else:
    sum = 0

# use while loop to iterate until zero
while num > 0:
    sum += num
    num -= 1
print["The sum is", sum]

Output:

Enter a number: 10
The sum is 55

Do comment if you have any doubts or suggestions on this Python sum topic.
