Using .append() with list vs dataframe

[Mark17]

using append I always get a message

Output:
FutureWarning: The frame.append method is deprecated and will be removed from pandas in a future version. Use pandas.concat instead.

I saw this but upon closer look it seemed like it was pertaining to appending one dataframe to another. I am appending a dictionary to a dataframe (to add a new row), which is why I thought the deprecation did not apply. I could certainly be wrong.
