Indexing allows us to access a row or column using the label. Check out my other articles if any of that sounds interesting. the same size as the index and its dtype must exactly match the w3resource. You should really use verify_integrity=True because pandas won't warn you if the column in non-unique, which can cause really weird behaviour. What is the difficulty level of this exercise?
