Extend and append

>>> A = ['Q','W','e','R']>>> A.extend (['T','y'])>>>a['Q','W','e','R','T','y']>>>Len (A)>>> B = ['Q','W','e','R']>>> B.append (['T','y'])>>>b['Q','W','e','R', ['T','y']]>>>len (B)

The similarity between extend and the Append method is that all new received parameters are placed behind the existing list. The extend method can only receive lists, and each element in the list is added to the original list.

The Append method can receive parameters of any data type and is simply appended to the list tail
