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

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] https://code.sololearn.com/c6EK5toPx4YV

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))

mycrochip brother ☹️ thanks for try but!!
1) output should be an array
2)your code is very complex ....a little bit hard for me to read
3) your code generate 5_test_error🥺

Click the link again. I have converted my result to an array.
If it works, I'll explain further.
Test it for now

Ok. Good.
You're welcome.
Anyways, the below will receive any number of rows and columns:

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

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

+ 3

Do you have some of the sample test...

+ 3

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

+ 3

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