[英]Rename Selected Cells Within Pandas String Vector
I am simply trying to rename some of the cells within the 'location' column in a pandas dataframe. 我只是想重命名熊猫数据框中“位置”列中的某些单元格。
The beginning of the dataframe looks like this: 数据框的开始看起来像这样:
Apr 25 ASHEVILLE
Apr 25 ASHEVILLE
Apr 25 ASHEVILLE
Apr 25 ASHEVILLE
Apr 25 ASHEVILLE
Apr 25 ASHEVILLE
Apr 25 ASHEVILLE
Apr 25 ASHEVILLE
Apr 25 ASHEVILLE
Apr 25 ASHEVILLE
Apr 25 ASHEVILLE
Apr 25 ASHEVILLE
Apr 25 ASHEVILLE N C
Apr 25 ASHEVILLE N C
Apr 25 ASHEVILLE N C
My best guess is: 我最好的猜测是:
postings.location = ["ASHEVILLE" for x in postings["location"] if "ASHEVILLE" in x]
but I get the following error message: 但我收到以下错误消息:
ValueError: Length of values does not match length of index
您可以将.loc
与.str访问器一起使用,并contains
:
postings.loc[postings.location.str.contains('ASHEVILLE'),'location'] = 'ASHEVILLE'
