What does pop mean in python?

pop() in python removes the element at the specified position in the list. At the same time, the removed element can be assigned to a variable. If the position parameter is not filled in, the last digit will be deleted by default

pop() deletes the key-value pair specified in the dictionary according to the key, and can assign the deleted value to the variable

For example:

 a = ["hello", "world", "dlrb"]
 b = ["hello", "world", "dlrb"]
 a.pop(1)
 b1 = b.pop(0)
 print(a)
 print(b1)

Output result:

['hello', 'dlrb']
hello

We remove the element at position 1 of list a

Remove the element at position 0 of list b and assign it to variable b1

 b = {
    "name":"dlrb",
     "age":25,
     "height":168
 }
 b1 = b.pop("age")
 print(b)
 print(b1)

Output results:

{'name': 'dlrb', 'height': 168}
25
