When I run the code python3 main.py to test my coding, it has the error as below

Can you paste your code here?

You cannot share your gitpod like this, you need to select sharing from the menu.

This is my code, but when running test it appeared the error below. Normally when I used the reshape() syntax, it worked, so I’m a bit confused here :

import numpy as np

def calculate(list):
# change list into an array
    arr = np.array(list)

# Reshape into 3x3
    matrix = arr.reshape(3, 3)

# Results
    calculations = {
        'mean': {
            'rows': np.mean(matrix, axis=1),
            'columns': np.mean(matrix, axis=0),
            'flattened': np.mean(arr)
        },
        'variance': {
            'rows': np.var(matrix, axis=1),
            'columns': np.var(matrix, axis=0),
            'flattened': np.var(arr)
        },
        'standard deviation': {
            'rows': np.std(matrix, axis=1),
            'columns': np.std(matrix, axis=0),
            'flattened': np.std(arr)
        },
        'max': {
            'rows': np.max(matrix, axis=1),
            'columns': np.max(matrix, axis=0),
            'flattened': np.max(arr)
        },
        'min': {
            'rows': np.min(matrix, axis=1),
            'columns': np.min(matrix, axis=0),
            'flattened': np.min(arr)
        },
        'sum': {
            'rows': np.sum(matrix, axis=1),
            'columns': np.sum(matrix, axis=0),
            'flattened': np.sum(arr)
        }
    }
    return calculations
calculate(list)

I’ve edited your post to improve the readability of the code. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (').

Can you please share a link to the exercise?

Are you getting an error because you are calling the function with an undefined variable?

calculate(list)

Call your function as instructed:

For example, calculate([0,1,2,3,4,5,6,7,8]) should return:

the link only works in 24 hours. And previously I shared but it didn’t work. So how can I fix this problem? From what I know, list is a keyword in python so we shouldn’t give a name as list.

while that is true , calculate works with a list of numbers, if you call it with something else, it will not work

so instead of calcuate(list), use one of the function calls described in the instructions, or don’t call it at all, the tests will do that
