Append add the entire data at once. The whole data will be added to the newly created index. On the other hand Extend as it name suggests extends the current array. for example

list1 = [123, 456, 678]
list2 = [111,222]

when append we get:

result = [123,456,678,[111,222]]

while on extend we get:

result = [123,456,678,111,222]

Append adds the entire data at once. The whole data will be added to the newly created index. On the other hand, extend, as it name suggests, extends the current array.

For example

list1 = [123, 456, 678]
list2 = [111, 222]

With append we get:

result = [123, 456, 678, [111, 222]]

While on extend we get:

result = [123, 456, 678, 111, 222]
