Why does 88 become 88.0 in a DataFrame?

Short answer. The other row is missing a value, so pandas fills NaN and the column goes decimal.

In a dictionary of lists, what do the keys become?

The column names.

Remember

Dict of lists: key = column
Dict of Series: labels match
List of dicts: one per row

Why did eighty eight become eighty eight point zero? Each dictionary in r is one row. The empty one gives N a N, so the column goes decimal. Dictionary of lists: keys are columns. Series: labels match. List of dictionaries: a row each.
