Python Day-Lists and list functions,Task

List:
[ ] --> Symbol
-->Collection of Data
-->Collection of Heteregeneous Data(different data types)
-->List is Index Based
-->List is Mutable(Changeable)

Ex: student_data = ['Guru Prasanna', 'B.Com', 23, True, 5.6]
indexing --> 0 1 2 3 4

Example: using while loop and for loop:

Output:

enumerate()-->Useful for index tracking
Enumerate is a built-in function in python that allows you to keep track of the number of iterations (loops) in a loop.

Syntax: enumerate(iterable, start=0)
--> Iterable: any object that supports iteration
--> Start: the index value from which the counter is to be started, by default it is 0

Example:

Output:

To prove list is mutable
Example:

Output:

List Functions:

1) append()-->Adds an element at the end of the list
2) insert()-->Adds an element at the specified position
3) remove()-->Removes the first item with the specified value(value based removal).
4) pop()-->Removes the element at the specified position(index based removal).

Example:

Output:

del keyword:
The del keyword is used to delete objects.(variables, lists, or parts of a list etc..)
-->Even del can be used to delete particular range.

Example:

Output:

Difference between del and pop:

del will remove the specified index.(keyword)
pop() removes and returns the element that was removed.(inbuilt method)

calculate total marks and percentage

Output:

Calculate Highest mark

Output:

Calculate lowest mark

Output:

isinstance(): The isinstance() function returns True if the specified object is of the specified type, otherwise False.
Example:1

Output:

Example:2

Output:

Example:3

Output:

Tasks:
1) contains n --> names
2) names have 5 letters
3) t --> names end with

Output:
