Using pandas library
#1
Hi,

I am a teacher and we are using python and pandas data structure. I am having trouble with this code:

import pandas as pd
numbers = pd.DataFrame([[3],[8],[4],[9],[14],[17]])
numbers.index = ["Odd", "Even", "Even", "Odd", "Even", "Odd"]
# check if 0 or 1
for i in numbers:
    i = numbers % 2
    print(i)
    if i == 0:
        numbers[1] = ["Y"]
    else:
        numbers[1] = ["N"]
I get i printed correctly but when i run the if statements and trying to add new column data i get this error:

Quote:Traceback (most recent call last):
File "C:/Users/ramit/PycharmProjects/grade10A1/lesson.py", line 15, in <module>
if i == 0:
File "C:\Users\ramit\PycharmProjects\grade10A1\venv\lib\site-packages\pandas\core\generic.py", line 1326, in __nonzero__
raise ValueError(
ValueError: The truth value of a DataFrame is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().

Please help,
Thanks.
