Answer 2

1. For the task you have to take two inputs: one for the filename, one for the column_name. Instead you used the example input.
2. You need only one pair of square brackets in the definition of arr.
3. arr should be a one-dimensional array, so you can print it in it's entirety.

Answer 3

1. Nos dan un archivo, por lo tanto debemos leerlo por medio de panda.
2. Convertimos en un array el nombre de la columna dada como segunda entrada usando ".values"
3. imprimimos todo el array

espero ser de ayuda :)

filename = input()
column_name = input()

import pandas as pd
df = pd.read_csv(filename)
arr = df[column_name].values
print(arr[:])

Hi Fataneh Tabarteh Farahani

#Just reorganize the code

import pandas as pd #is important to start like this

filename = input() #this was given
column_name = input() #this was given

df = pd.read_csv(filename) #to read the file
arr = df[column_name].values #to get the data and output it as requested

print(arr)
