Problem with UpdateSourceTrigger=PropertyChanged and StringFormat in WPF

℡╲_俬逩灬. 提交于 2019-12-03 08:59:45

How to convert wav to flac from python?

I have a DataFrame like this: Name asn count Org1 asn1,asn2 1 org2 asn3 2 org3 asn4,asn5 5 I would like to convert my DataFrame to look like this: Name asn count Org1 asn1 1 Org1 asn2 1 org2 asn3 2 org3 asn4 5 Org3 asn5 5 I know used the following code to do it with two columns, but I am not sure how can I do it for three. df2 = df.asn.str.split(',').apply(pd.Series) df2.index = df.Name df2 = df2.stack().reset_index('Name') Can anybody help? Carrying on from the same idea, you could set a MultiIndex for df2 and then stack. For example: >>> df2 = df.asn.str.split(',').apply(pd.Series) >>> df2

I know my question sounds a little bit like a shopping request, but I honestly believe that many people could find it useful.
