[SOLVED](by master)[code error] Help me find the mistake??

Question

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]

Use mean function instead of self calculated average.

import numpy as q
n, p = [int(x) for x in input().split()]
a = []

while n > 0:
#s = sum([float(x) for x in input().split()])
s = q.array(input().split(), dtype = float)
mean = s.mean()
a.append(round(mean, 2))
n -= 1

print(q.array(a))

You're welcome. I learned a lot too

Answer 13

Caleb Guerra Ortega Molina Sánchez

So learn python and Know NumPy. Btw how did you know "NumPy" if you don't know?

Answer 14

Firstly, you are required to receive three row inputs

1.) n_rows, n_cols --> np.shape()
2.) row_1: [00 01] --> row_0, col_0; row_0, col_1
3.) row_2: [ 10 11 ] --> row_1, col_0; row_1, col_1

Answer 15

Do you have some of the sample test...

Answer 16

Oh. I see. I will loop through the number of rows

Answer 17

I will walk you through all the steps block by block when you're free.
