在指定字符后删除字符串状索引的字符

Question

Is there a way to remove the characters after a specified character in an index for a Pandas DataFrame?

I have been using the censusdata package for some data analysis and it outputs the data to a DataFrame with the index as the censusgeo info (eg Anaheim city, California: Summary level: 160, state:06 place:02000) I want to change the index to only be 'Anaheim city, California'. What is the best way to do this? Is it possible in python? Could it be easier to do in html? I am already using DataFrame.to_html() as my output.

Thanks

An example:

"Anaheim city, California: Summary level: 160, state:06 place:02000".split(":",maxsplit=1)[0]                        
Out: 'Anaheim city, California'

Replace the old index with a new one:

newindex= [ idx.split(":",maxsplit=1)[0] for idx in df.index ]
df.index=newindex
