Can anyone tell me why my solution is wrong even though it works for me?

Question

I wan to solve the Module 1 Quiz 'Average of Rows' of the Data Science course.

https://www.sololearn.com/learning/eom-project/1093/111

I end my code and test it apart in the code playground, but when I run my code it just meet 3 of the test cases and I do not know why.

This is my code:

import numpy as np

n, p = [int(x) for x in input().split()]

list = []
for i in range(n):
row = [float(j) for j in input().split()]
list.append(row)

arr = np.array(list)
arr = arr.reshape((n,p))

print(arr.mean(axis = 1))

Please anyone tell me why it do not meet the whole of the cases...

Answer 1

U need get mean every row, when u generate list variable, for this u can get row.mean() or row.sum()/p. U don't need reshape. And don't forget about round on 2 char

Answer 2

And finally if u have after questions, u can look on my solution

Answer 3

Thanks Илья Мирошник, I try rounding the mean to two floats and it works, so thank you again :D

Answer 4

Okay thanks a lot ;D
