Results/What Does it Do?
cmp(list1, list2)
len(list)
max(list)
min(list)
list.append(obj)
list.count(obj)
list.extend(seq)
list.index(obj)
list.insert(index, obj)
list.pop(obj=list[-1])
list.remove(obj)
list.reverse( )
list.sort([func])

Answer 1

Explanation for each of the given:

1) cmp(list1, list2):

it is the inbuilt function in python. it takes two arguments

lets denote 1st argument as "n" and second argument as "m"

if "n<m" it will return "-1" as output

if "n==m" it will return "0" as output

if "n>m" it will return "1" as output

2) len(list)

len(list) will display the length of the list

3) max(list)

max(list) displays the maximum element or highest element in the list

4) min(list)

min(list) will display the minimum element or lowest element in the list

5 )list.append(obj)

list.append(obj) will add the element into the list

for example if we give "list.append(5)", The element "5" will be added into the list

6) list.count(obj)

list.count(obj) will count the number of occurences of the element in the list

7) list.extend(seq)

list.extend(seq) will take a list as an argument and it will combine the elements of the both lists i.e original list and list given as argument and displays the whole element in a list

8) list.index(obj)

list.index(obj) will display the index or position of the element in the list

indexes in the element starts from "0" position

9) list.insert(index, obj)

list.insert(index, obj) will add the element given in the argument in the index position given in the argument

for example if we give "list.insert(5,15)" it will add the element "15" in the "5th" position of the list

10) list.pop(obj=list[-1])

list.pop(obj=list[-1]) will delete the element in the "0 th" position of the list

11) list.remove(obj)

list.remove(obj) will remove or delete the argumented element from the list

for example "list.remove(5)" will delete the element "5" from the list

12 )list.reverse( )

list.reverse( ) will display the list in the reverse order

if the original list is "[5,6,7,8,9] ", the reversed list will be displayed as "[9,8,7,6,5]"

13) list.sort([func])

list.sort([func]) will sort the list in the ascending order

Proof for all the above given:
