Most of the responses given demonstrate how to remove the duplicates, not find them.

The following will select each row in the data frame with a duplicate 'name' field. Note that this will find each instance, not just duplicates after the first occurrence. The keep argument accepts additional values that can exclude either the first or last occurrence.

df[df.duplicated(['name'], keep=False)]

The pandas reference for duplicated() can be found here.
