Slicing a List in Python
If  you  want  to  perform  a  slice  in  Python,  you  have  to  stipulate  the  first  and  last  index  of  the
elements  in  the  list.  Similar  to  the  range()  function  we  use  previously,  Python  halts  at  one  item
before  the  second  index  you  stipulate.  To  display  the  first  five  elements,  you  have  to  request
indices from 0 to 5. In this situation, this would return the following elements 0, 1, 2, 3, 4, and 5.
The following are team members in Manchester United Football club
united_players =[ “Rashford,” “Young,” “Pogba,” “James,” “De Gea”]
print(united_players [1:4]
The second line prints a slice of the element in the list, which comprises of the following players.
“Young,” “Pogba,” “James,” “De Gea”
If you mistakenly forget the first index when slicing a list, Python spontaneously begins your slice
at the start of your list. For instance,
united_players =[ “Rashford,” “Young,” “Pogba,” “James,” “De Gea”]
print(united_players [:4]
Since there is no starting index, the output will be:
“Young,” “Pogba,” “James,” “De Gea”
The same thing applies if you omit the last index of the list. For instance, you want to start your
index at 2 while omitting the second index.
united_players =[ “Rashford,” “Young,” “Pogba,” “James,” “De Gea”]
print(united_players [2:]
Python will return the following value:
“Pogba,” “James,” “De Gea”
With this, you can print out all elements in a list irrespective of the length and its position. You can
use a negative index, but it recalls a number from list end. For instance, our goal to display the last
four United players in our list
united_players =[ “Rashford,” “Young,” “Pogba,” “James,” “De Gea”]
print(united_players [-4:]
This will print the last four players
“Young,” “Pogba,” “James,” “De Gea”
