Data Science - Average of Rows

Question

hello, i am trying to solve the code challenge at the end of chapter1 of the data science course and i can only pass 3 out of 5 tests and i can't figure out why my code is not working in all the cases

#input of the first line containg the size of rows(n) and columns(p) of a data set
n, p = [int(x) for x in input().split()]

my first approach was to read the next lines containg the data for the data set and add them into a list and transform that into a ndarray

import numpy as np
myList = []
for index in range(n):
p1 = [float(x) for x in input().split()]
p1=[float("{:.2f}".format(i)) for i in p1]
myList.append(p1)
myArr = np.array(myList)
myArr.reshape(n,p)
print(myArr.sum(axis=1)/p)

with this method i convert the string value in a float one and then impose a 2 digits float number format. i then sum by row and display the average

can someone help me understand where i might not see a bug in my flow?

Answer 1

Remove line 38 – do not round the input values.

Calculte the mean simy by using the .mean() method. Round the result by 2 places, using the .round(2) method

Answer 2

That is exactly what "put your code in a script on sololearn playground" means ;)

Answer 3

Great that you solved the issue!

Answer 4

Please put your code in a script on sololearn playground instead of copying it into the description.

Go to Code section, click +, select Python, insert code. Come back to this thread, click +, Insert Code, sort for My Code Bits, select your code.

i could not perform the "click +, Insert Code, sort for My Code Bits, select your code"
because i can't find the + button, but i posted my code on the playground and here is the link.

It worked, thanks! I tried using mean but I thought that the problem must have been in the rounding but could not work around that issue. Thank you a lot
