Built-in Methods

Next Post

Python includes many built-in methods for use with list as shown as follows

1. cmp(list1,list2)         - It compares the elements of both lists, list1 and list2

2. len(list)                     - It Returns length of string or set

3. max(list)                   - It Returns item that has Maximum value in a list

4. min(list)                    - It Returns item that has Minimum value in a list

5. list(seq)                     - It converts a tuple into a list

6. list.append(item)       - It adds the item to the end of the list

7. list.count(item)          - It returns number of times the item occurs in a list

8. list.index(item)          - It returns the index number of the item.

9. list.insert(index,item) - It inserts the given item on the the given index number in the list

10 list.reverse()              - It reverse the position(index number) of the items in the list

11. list.sort([function])   - It sorts the elements inside the list and uses compare function if provided

12. list.extend(seq)         - It adds the elements of the sequence at the end of the list 

 

Lab Assignment:

Write a python script to use frequently used built-in methods(atlest five methods)

a=[40,5,10,20,10]
print(a)

ch='y'
while(ch=='y' or ch=='Y'):
    print("1. Min and Max")
    print("2. Append Element")
    print("3. Insert Element")
    print("4. Delete Element")
    print("5. Reverse Elements")
    print("6. SOrt List")

    choice=int(input("Enter Your choice : "))
    if(choice==1):
        print("Max Element is %d and Min Element is %d" %(max(a),min(a)))
    elif(choice==2):
        a.append(5)
        print(a)
    elif choice==3:
        a.insert(2,25)
        print(a)
    elif choice==4:
        del a[1]
        print(a)
    elif choice==5:
        a.reverse()
        print(a)
    elif choice==6:
        a.sort()
        print(a)
    else:
        print("Wrong Choice")

    ch=input("Want to continue(Y/N) : ")


print("Successful!!")
