Pandas split column into multiple columns by comma

In case someone else wants to split a single column (deliminated by a value) into multiple columns – try this:

series.str.split(',', expand=True)

This answered the question I came here looking for.

Credit to EdChum’s code that includes adding the split columns back to the dataframe.

pd.concat([df[[0]], df[1].str.split(', ', expand=True)], axis=1)

Note: The first argument df[[0]] is DataFrame.

The second argument df[1].str.split is the series that you want to split.
