]Can you describe what you mean by this:

Can someone help me make a class for that as screenshots?
1)More parameter checking only copy a class.
2)when check file without goldensample how to handle this issue.

I might understand what you mean with goldensample. You are wondering what to do if this is an empty dataframe.

 df = pd.read_csv(csv_add, header=2)
    df = df[df["Lot Code"].str.contains("golden")]

I would have the readcsv() function return None if is no golden data in the file.

import pandas as pd


def read_csv():
    df = pd.DataFrame(
        {"Lot Code": ["G", "B", "G"], "Numbers": [5, 6, 7], "Letters": ["A", "B", "C"]}
    )
    df = df[df["Lot Code"].str.contains("G")]
    if len(df) == 0:
        return None
    return df["Numbers"].values, df["Letters"].values


x = read_csv()
if x is None:
    sg.popup("Error", "There's no golden data!")
else:
    numbers, letters = x
    print(numbers, letters)
