Two methods of finding element position in python list

Sequence is the most basic data structure in Python. Each element in the sequence is assigned a number - its position, or index. The first index is 0, the second index is 1, and so on. Python has six built-in types of sequences, but the most common are lists and tuples. Today I would like to share with you two ways to find the location of elements in python list

1. Access a single element through index positioning, listname represents the name of the list, and index represents the index value of the element to be searched.

Grammatical structure

 listname [index]

2. Access multiple elements by slicing, listname represents the name of the list, and index represents the index value of the element to be searched.

Grammatical structure

 listname[ start : end :step]

example

 list  = [ 'Da Wei' ,  'Xiao Wei' ,  'Xiaowei' , one hundred and twenty-three ] print ( list [ zero ])   #The first element of the output list
 print ( list [ one : three ])   #Output the second to third elements
 print ( list [ two :])   #Output all elements from the third to the end of the list
