Using .append() with list vs dataframe

[deanhystad]

DataFrame.append(other, ignore_index=False, verify_integrity=False, sort=False)[source]¶
Append rows of other to the end of caller, returning a new object.

list.append(x)
Add an item to the end of the list. Equivalent to a[len(a):] = [x].

Notice that DataFrame.append says it returns a new object. Python.list.append says nothing about a return value, and it returns None.

The word is the same. Use is similar. Results are completely different.
