How to Remove Instances of Particular Values from a List
At times, you may decide to remove a particular value from a list. Well, you
remember  the  remove()  function  we  talked  about?  This  works  perfectly
well; however, what if we want to remove values that appear twice in a list.
That also is possible to do in Python.
For  instance,  here  is  a  list  of  footballers'  names  with  “Oscar”  repeated
thrice.  You  can  use  a  while  loop  to  remove  all  instances  of  the  name
pending when there is no “Oscar.”  Check the code to see as that is possible.
footballers  =  [“Oscar,”  “Messi,”  “Vardy,”  “Oscar,”  “Ronaldo,”  “Oscar,”
“Fred,” “Lampard,” “Terry”]
print(footballers)
while “Oscar” in footballers:
footballers.remove(“Oscar”)
print(footballers)
The logic of the program is very easy to understand. We assign the variable
footballers  with  various  value,  but  “Oscar”  repeated  thrice.  It  prints  the
names of the footballers. Then the code enters the while loop because we

---

have Oscar in our list in more than one instance. Inside the loop, the first
instance  of  Oscar  returns  to  the  while  line  before  it  reenters  the  loop  to
ascertain if there is another Oscar. It continues in such a manner until the
list is empty. The output for our program will be”:
[“Oscar,”  “Messi,”  “Vardy,”  “Oscar,”  “Ronaldo,”  “Oscar,”  “Fred,”
“Lampard,” “Terry”]
[“Messi,” “Vardy,” “Ronaldo,” “Fred,” “Lampard,” “Terry”]
