[英]pandas error: value is trying to be set on a copy of a slice from a DataFrame
df_play = pd.read_csv("players_stats_by_season_full_details.csv")
VC = df_play[df_play["League"] == "NBA"]
VC
VC["FT_Miss"] = VC['FTA'] - VC['FTM']
錯誤信息：
A value is trying to be set on a copy of a slice from a DataFrame.
Try using .loc[row_indexer,col_indexer] = value instead
VC不是數據幀，它是原始數據的一部分，這意味着它只是一個指向 df_play 的指針
嘗試;
VC = df_play[df_play["League"] == "NBA"].copy()
