How to simulate hidden test cases ?

In a question related to data science the 5th hidden test case is failing?How can we access this? DATA SCIENCE : 8 Average of Rows https://code.sololearn.com/cPj3C3q7thFh/?ref=app

You can access the hidden test cases. Read the instruction carefully and correct your code

G'day Sanjay Kamath as Lisa said (with a typo?) "You can't access the test cases". But you can debug your code for logic flaws, most common are: array not big enough, or failing to check for zero values. EDIT 2: task instructions 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]

The output needs to match exactly the sample in the task description. Use numpy as suggested in the data science course, not array

G'day Sanjay Kamath your code must be really close to correct, only test case 5 isn't passing! I don't know enough about python to help you beyond: copy your code into a "code bit" and do some debugging with inputs that you know the results for. I would try lines with a zero, lines with a negative, etc etc. I don't think you need to worry about your array size. Your output format is ok for the other 4 test cases, but perhaps test case 5 has a single row of values?? When do you add the space between output floats? Sorry that I can't help more, good luck! EDIT: I reckon it is your output formatting. Try testing with 5 2 1.5 1 2 2.9 2 2 1.5 1 2 2.9
