错误使用枚举

Question

I have a problem with my code: I have this array of tot

[112 100  22  90  12  48 115  85  13  40  99  93 100  27  21  14  23 100]

I defined a random solution function:

def randomSolution():
    somma = 0;
    for i in enumerate(tot): 
        if somma<=3600: 
            countS[i] = 1
            somma = somma + tot[i]
        else: 
            break
    return countS
rand_sol = randomSolution()
print(rand_sol)

but Jupiter lab underlines me

Index Error: too many indices for array.

Can someone help me?

I'm trying to be very forgiving of the way this questions was posed. I take it you are just trying to understand how to populate an array called countS

1. First things first, your array has no delimiters, which is a non-starter. I've added commas to help us get over this hurdled.

2. You never provided countS , so I just created an empty list for us to fill.

3. Because countS is originally an empty list, you can't index it iteratively. I replaced countS[i] = 1 with countS.append(1) to append the new value iteratively to the list.

4. You may need a refresher on how to use enumerate because you are currently only unpacking the a single value. enumerate() returns the index position in list and the value at the index - so you need to unpack both with something like for i, value in enumerate(tot):

Here is the code that I got working - I hope this helps. In the future, please provide everything necessary to run your code so that we can help you more effectively.

tot = [112, 100, 22, 90, 12, 48, 115, 85, 13, 40, 99, 93, 100, 27, 21, 14, 23, 100]
countS = []

def randomSolution():
    somma = 0;
    for i, value in enumerate(tot): 
        if somma<=3600: 
            countS.append(1)
            somma = somma + tot[i]
        else: 
            break
    return countS
rand_sol = randomSolution()
print(rand_sol)

output

[1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1]
