Adding tutorial on tuples operations to the pandas lab

For c_statistic (UNQ_C8), it would have been great to have some introduction on tuples operations in the labs (for instance with the pandas introduction)

Hello @Alevesque,
Thanks a lot for bringing this up. Please feel free to keep making improvement suggestions as this improves every learner’s experience. I would like to share several helpful links if there are other learners feeling challenged about tuples operations on pandas and tutorials on this topic.
