是否可以使用pandas DataFrame创建多行单元？

Question

我的SQLite表中的某些单元格超出了终端中熊猫显示设置的长度。有没有办法使长信息换行到另一行？

这是我的代码：

def view_work(self, CID):
    pd.set_option('display.max_columns', None)
    sq="SELECT * FROM Work_Done WHERE CID=?;"
    df=pd.read_sql_query(sq, self.conn, params=CID)
    df=df.set_index("Date")
    df=df.sort_values(by=['Date'])
    return df

这是当前DataFrame的输出：

Date                                                Work_Done Parts_Installed /                   
2018-12-20  Installed computer and removed all of the pre-...                   
2018-12-22  Worked on getting Antivirus instlaled. Set up ...            None    

我想要的是：

Date                                                Work_Done Parts_Installed /                   
2018-12-20  Installed computer and removed all of the pre-
            installed software. Joined computer to domain 
            and setup network applications for user.           
2018-12-22  Worked on getting Antivirus installed. Set up a  
            printer/fax machine. Loaded software for user and
            showed them how to use the computer.                          None    

当“ Work_Done”单元超过最大显示长度时，是否可以自动换行？

Answer 1

pd.set_option('display.max_colwidth', None) 应该为您完成这项工作。它将列宽设置为无限制而不会溢出（这意味着没有“...”但有自动换行符）。签入pandas docs。
