Error on pandas module

[simonnchong]

I can print the result in the console without any error but AREPL reported many errors message.

Actually, I'm not able to reproduce this w/ Windows 10, python 3.10, and pandas 1.5.2. What version of pandas are you using?

import pandas as pd

data = pd.read_csv("C:\\dev\\misc\\candel\\weather_data.csv")


print(data[data["day"] == "Monday"])
#* or
print(data[data.day == "Monday"])

weather_data.csv:

day,temp,condition
Monday,12,Sunny
Tuesday,14,Rain
Wednesday,15,Rain
