#To select rows whose column value is in an iterable array, which we'll define as array, you can use isin: array=['yellow','green'] df.loc[df['favorite_color'].isin(array)] 根据多列条件选择行: #Toselecta row based on multiple conditions you can use &: array= ['yellow','green'...
You can usemultiple conditionsto select data from a multi-index DataFrame: # Select rows where A > 0.5 in level 1 index 2 and B < 0.3 in level 1 index 3 df_complex = df_sorted.loc[((df_sorted.index.get_level_values(0) == 2) & (df_sorted['A'] > 0.5)) | ((df_sorted.ind...
Filter by Column Value:To select rows based on a specific column value, use the index chain method. For example, to filter rows where sales are over 300: Pythongreater_than = df[df['Sales'] > 300] This will return rows with sales greater than 300.Filter by Multiple Conditions:...
