Learning Python: The Ultimate Guide for Beginners to Coding with Python with Useful Tools

Using Loop in a Slice
Python allows the use of for loop in a slice to go through a subset of elements in the list. We can
create a loop to pass through the first four players on our list and display their names. Let us see
how that works.
united_players =[ “Rashford,” “Young,” “Pogba,” “James,” “De Gea”]
print (“My favorite Manchester United Players are:”)
for players in united_players [ :4]:
print(players.title())
Rather than the interpreter looping through the full list of players in line 3, it loops only through
the first four players in the team. Then our output will be:
My favorite Manchester United Players are:
Rashford
Young
Pogba
James
Slice comes handy in various situations, such as when you want to add the final score of a player in
a game when working with data or building a website application.
Tuples
If you want to store items, which can change during the course of the program, then the list works
perfectly for this situation. Modifying data or a list is very important when working with various
applications or creating web applications. Notwithstanding, at times, you may want a list of items
whose  value  doesn’t  change  throughout  the  program.  In  such  a  situation,  you  can  use  a  tuple  to
replace  using  a  list.  In  Python,  we  call  values,  which  cannot  change  throughout  the  life  of  the
program as immutable. Therefore, an immutable list can also be known as a tuple.
