List

List values must be given within [] square braces.

List is mutable (modifiable)

• Tuple values must be given within () parenthesis.
• List values must be given within [] square braces.
• List is used to store group of values under same name.
• List allows duplicate values.
• List can store group of different type of values.
• List is indexed and ordered.

solution:

    <class 'list'>
    marks= [41, 86, 94, 74, 41, 58]
    41
    86
    94
    74
    41
    58

functions which works on tuple, list, set and dict.

solution:

    minimum= 41
    maximum= 94
    sum= 415
    length= 6
    sorted marks= [41, 58, 62, 74, 86, 94]
    Traceback (most recent call last):
      File "C:/Users/Darshan /Desktop/functions which works on tuple, list, set and dict..py", line 9, in <module>
        print('marks=',marks)
    NameError: name 'marks' is not defined. Did you mean: 'vars'?

we can add 2 or 3 list together

solution:

   d= [2, 4, 6, 1, 3, 9, 12, 4, 6, 8]

List supports repetition

solution:

    b= [2, 5, 9, 2, 5, 9, 2, 5, 9]

List supports slicing

solution:

    [6, 8, 10, 12, 14, 16]
    [10, 12, 14, 16, 18, 20]
    [2, 4, 6, 8, 10, 12]
    [12, 14, 16, 18, 20, 22, 24, 26, 28, 30]
    30
    28
    [6, 10, 14, 18, 22]
    [2, 6, 10, 14, 18, 22, 26, 30]
    [4, 8, 12, 16, 20, 24, 28]
    [30, 28, 26, 24]
    [30, 28, 26, 24, 22, 20, 18, 16, 14, 12, 10, 8, 6, 4, 2]

List functions

List is mutable(modifiable)

• Can insert single value using append function.
• It adds the given value at the end of list. can insert single value using append function.

solution:

   [20, 80, 40, 20, 50, 80, 20, 15, 25, 35]

can delete single value from list

solution:

   [80, 40, 20, 50, 80, 20]

can update value

solution:

   [20, 80, 40, 60, 50]

Clear Function

solution:

   a= [10, 20, 50, 60, 50, 20.3, '#', 'list']
   a= []

Copy Function

Copy Function: This function used to copy entire list values to another list.

solution:

   a= [20, 23.5, '#', 'Hello']
   b= [20, 23.5, '#', 'Hello']

Count Function and Index Function

• Count Function: This function gives number of occurrences of gives element.
• Index Function: This function gives index of given values.

solution:

    3
    2
    1
    0
    0
    1

Extend Function

Extend Function: Extend used to add multiple elements at the end of the list.

solution:

    e= [10, 20, 30, 40, 2, 4, 6, 8]

Insert Function

Insert Function: used to insert the element at given posotion.

solution:

   a=[10,50,40,80,100,30]

pop function

pop function: pop used to remove last item in the list.

solution:

   p=[10,20,40,60]

Remove Function

Remove function used to remove given element from the list.

solution:

   p= [10, 20, 70, 30]

Sort Function

Sort Function: used to sort the elements in ascending order.

solution:

   p= [10, 20, 30, 50, 60, 70, 80]

Reverse Function:

Reverse Function: used to reverse the elements in the list.

solution:

    p= [30, 70, 50, 20, 60, 10, 80]
