[Pandas] 筛选出指定字段包含某个特定值的所有行

导入数据

import pandas as pd
 
df = pd.DataFrame([['liver','E',89,21,24,64],
                   ['Arry','C',36,37,37,57],
                   ['Ack','A',57,60,18,84],
                   ['Eorge','C',93,96,71,78],
                   ['Oah','D',65,49,61,86]
                  ], 
                   columns = ['name','team','Q1','Q2','Q3','Q4'])

df

问题: 筛选出'team'字段包含'C'值的所有数据行

cteam_data = df[df["team"].str.contains("C")]

cteam_data 

问题扩展: 删除'team'字段包含'C'值的所有数据行

import pandas as pd
 
df = pd.DataFrame([['liver','E',89,21,24,64],
                   ['Arry','C',36,37,37,57],
                   ['Ack','A',57,60,18,84],
                   ['Eorge','C',93,96,71,78],
                   ['Oah','D',65,49,61,86]
                  ], 
                   columns = ['name','team','Q1','Q2','Q3','Q4'])


# 删除'team'字段包含'C'值的所有行
df = df[~df["team"].str.contains("C")]
