I don't understand this one.

Question

nums=[1,2,3,4,5]nums [3]=nums [1]print (nums [3])how the answer could be 2?

Answer 1

Because with "nums [3]=nums [1]" you make the third number ( which, as we know, it's actually the forth since you have to start counting from 0, not 1) , in this case 4, turn into the first number (actually the second) , which is 2.

Answer 2

after executing nums[3] =nums[1], the list is changed to [1,2,3,2,5]. since index starts from 0.

Answer 3

list 3 index means 4 th position in list and 1 index means 2 position. now compare ...

Answer 4

List index 3 has value of 4 and is replaced by value of index 1 which is 2. Now position 3 has value of 2, copied from index 1.
Hope you understood it.

Answer 5

Cuz nums[0]=1,nums[1]=2,nums[2]=3,nums[3]=4,nums[4]=5.

Answer 6

Жалко что комментарии нет на русском

Answer 7

because when u do this
nums [3]=nums [1] .... the num [3] value will over write and num [3] shows the value of num[1]

Answer 8

You replaced the 4 with a 2, but the 2 itself remained unchanged.

Answer 9

Test it out.
