Can any one explain indexing in python ?
index: 0, 1, 2, 3 value=[10, 23, 3, 5] index: -4, -3, -2, -1
can you give an example of what you don't understand
Sohan Singh , > 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.
Sohan Singh 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) 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
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.
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...
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.
Like how to cheak which element which position ex like [1,23,3,5] this
It is the position of a data type
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
What Is formula of indexing bro?
index starts from 0 to n
