Duplicating Row Based on Cell Value/Content

Question

Currently attempting this with Pandas, but if there is a better way I'm all ears. I have a csv file that looks something like this:

column1	column2
value	value
value	value1, value2
value	value

What I would like to do is:

1. Check column2 for rows that have more than one value (e.g. "value, value").
2. Create a new row with value2 and remove it from it's original row:

column1	column2
value	value
value	value1
value	value2
value	value

I'm not sure what is the best way to determine if a cell in column2 has 2 values, maybe something like this:

for i in df.column2:
    if "," in i:

But I'm not sure how to capture that row and write it.
