Dataframe根据某一列的值获取满足条件的行的其他列的值

from pandas.core.frame import DataFrame

ls_id = [\'1\', \'2\', \'3\', \'4\']
ls_score = [89, 65, 73, 94]
df = DataFrame({\'id\': ls_id, \'score\': ls_score})  # 用列表构造Dataframe
print(df)
print(\'----------------------\')
df_id_column = df.id.copy()
print(\'df_id_column的类型为:  \',type(df_id_column))
print(df_id_column.values)
print(\'----------------------\')
print(\'输出id为3的score:\')
print(df.loc[df[\'id\']==\'3\',\'score\'])
