Data science average of rows

Question

Data Science - Average of Rows
In a matrix, or 2-d array X, the averages (or means) of the elements of rows is called row means.
Task
Given a 2D array, return the rowmeans.
Input Format
First line: two integers separated by spaces, the first indicates the rows of matrix X (n) and the second indicates the columns of X (p)
Next n lines: values of the row in X
Output Format
An numpy 1d array of values rounded to the second decimal.
2 2
1.5 1
2 2.9
Sample Output
[1.25 2.45]
My Code:
import numpy as np
n, p = [int(x) for x in input().split()]
my_list = []
for i in range(n):
my_list.append(list(float(x) for x in (input().split())))
my_list_ar = np.array(my_list)
my_list_ar.reshape(n, p)
print(np.around((my_list_ar.mean(axis=1)), decimals=2))
Input
3 2
1 2
1 0.5
1 0.3
Your Output
[1.5 0.75 0.65]
Expected Output
[1.5 0.75 0.65]
It says the error is because there is a space between 1.5 and 0.75

Answer 2

I made a test on the playground of my own code, and it also produced a double space between 1.5 and 0.75
It's also important that the input is correct, or else you end up getting an error about something in numpy that is deprecated.

Answer 3

I made some tests on the test cases with the same code that earlier passed all test cases.
First, it failed test case 2, 3 and 4. Then I converted the output to a string without the extra space, and then it passed test case 2, but it still failed 3 and 4. That's weird.

Answer 4

Hi!, did you managed to solve it? I'm haing the same problem with the extra spacing, and i'm still unable to figure out how to solve it :(
