Answer 1

Abdollahi Mohammed python creates the same empty list and copies it n times(rows) in your 'ls'.
To better understand what is happening, try changing a single element in 'ls', you will see it gets reflected in all rows.

While in 'lst', they are n separate lists. Also, you can change n-1 in ur code to -1

For in depth explanation: refer python shallow copying and deep copying.
