The select method does not handle identical column names being passed as arguments.

For example:

>>> df = DataFrame('table1')
>>> df.select(['col1', 'col1'])

To work around, use the assign method to provide an alias.

# c1 and c2 both refer to the col1 column
>>> df.assign(c1 = df.col1, c2 = df.col1)
