index: -4, -3, -2, -1

Answer 2

can you give an example of what you don't understand

Answer 3

> we can use the list index() method to check for the index number of an element from the list.
> we can also get all of the indexes of the elements of the list by iterating over the list. use a counter that will be updated in each loop iteration.

Hii mate !!
May this help you and good luck.
#How to access elements in string ?
"""Two ways:
1. indexing
2. slicing
index : index is used to access single element in the string
slicing : slicing is used to access group of elements in the string
"""
#name = "index value"
# 012345678910
#can also use negative value to access element backward.
#syntax: print(var_name[index])
name = "karan singh"
print(name[4])
print(name[-7] )
#slicing
"""slicing : slicing is used to access group of elements in string """
name = "karan singh"
print(name[0:4])
print(name[:-4:-1])
print(name[0:0])
print(name[-1:-5:-3])
Run_this ="udohyheuvkomlri"
print(Run_this[::-2])
#Done

Answer 5

Sohan Singh ,
you have done the *python core* tutorial and also some other python tutorials, so i am sure that you are able to solve this problem by yourself.

Answer 6

indexing is simply a way of allocating identifiers especially numbers to elements in an array.
For example:
In the code bellow, we have an array(list) that stores the value of numbers from 1 to 10. If we want to use the elements in it, we have to index it, that is like giving it a position. Starting from the left, to the rights, all the elements in the list start from 0 upward...
#list
list_of_numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
#Indexing will be 0, 1, 2..
#where 1 in the list marches to the index 0
Also, note: to find the index of an element, we can also use the index() function in python...

Answer 7

You can use the index method to get an index number for the first occurrence For a list a=[1,23,3,5], a.index(3) would return 2.

Answer 8

It is the position of a data type

Answer 9

Imagine that the index is your toy car collection, from 1 to 10 cars. Each car has a number from 1-10.You forgot where did you put the first toycar you ever bought.
lets take a look at this command for example:
Car = [1,2,3,4,5,6,7,8,9,10]
#This is the list of every car you bought, starting from 1 to the right is the first-last car you ever bought from ur collection(list), from lowest to largest.You wanna know what is the first car u ever bought in your collection so, you need to print it using index.
print(Car.index(1))
#This will tell you the position of the first car you ever bought in your collection
However, when printing the first number on the index, it always start at 0 unless you wanna print the another number after the first number on the list.
the program in the example prints 0 to the screen, that is the position of the car.
another code for sample:
list = [5,7,9,11]
print(list.index(9))
#Output 2

Answer 10

index starts from 0 to n
